WEBVTT 00:00:00.160 --> 00:00:05.279 i remember seeing in the bio settings of 00:00:03.280 --> 00:00:10.800 this motherboard this very expensive motherboard an option for pci express 00:00:09.360 --> 00:00:15.440 hot swap which i have never personally tried 00:00:12.400 --> 00:00:18.000 before but what it sounds like is just 00:00:15.440 --> 00:00:22.560 putting pci express cards in and taking them off while this system is running 00:00:20.800 --> 00:00:27.920 is that going to work wow i actually super don't know so let's 00:00:25.760 --> 00:00:32.719 find out after i tell you about pia private 00:00:30.960 --> 00:00:36.160 internet access encrypts all your internet traffic and uses a safe 00:00:34.320 --> 00:00:40.520 protected ip and it's got a ton of other useful features you can check it out now 00:00:37.840 --> 00:00:45.499 at the link below 00:00:48.559 --> 00:00:54.800 so uh there's lots of things in a computer that are hot swappable and that 00:00:52.000 --> 00:00:59.520 we hot swap every day so usb for example even though you would safely remove the 00:00:56.960 --> 00:01:03.680 device theoretically with the you know little prompt in the bottom corner 00:01:01.680 --> 00:01:07.439 anytime you are taking something out or putting something in 00:01:05.280 --> 00:01:11.600 without powering off first it is technically hot swap and some standards 00:01:10.080 --> 00:01:15.680 that don't support hot swap like ps2 keyboards for 00:01:14.720 --> 00:01:20.479 example you can still for the most part hot swap 00:01:18.080 --> 00:01:27.119 them without any ill effects with all of that said there are components out there 00:01:22.960 --> 00:01:30.240 that either cannot be hot swapped or 00:01:27.119 --> 00:01:32.000 have to be specifically designed for hot 00:01:30.240 --> 00:01:36.799 swap in order to function with it even components like 00:01:34.400 --> 00:01:40.000 cpus and memory can 00:01:37.840 --> 00:01:45.200 actually be hot swap but that's more of a server level feature where the system 00:01:42.720 --> 00:01:50.399 itself and usually some kind of a of a daughter board that that slides in or 00:01:47.680 --> 00:01:55.680 whatever else has to be designed for it because you can't just you can't just 00:01:52.960 --> 00:01:58.159 cut power to uh to a computer component and expect everything to operate 00:01:57.119 --> 00:02:03.680 normally now as for pci express 00:02:02.000 --> 00:02:06.880 i confess i haven't done a ton of research coming 00:02:05.360 --> 00:02:13.680 into this so it's possible that the device itself 00:02:10.160 --> 00:02:16.000 also needs to be designed for hot swap 00:02:13.680 --> 00:02:19.840 but then it's possible that it doesn't i don't know where we're 00:02:17.760 --> 00:02:22.959 going to find out today for those of you wondering the the titan 00:02:21.920 --> 00:02:26.800 x here i will not be hot swapping that that's 00:02:25.200 --> 00:02:31.200 just here so that we have a display output i think it's time for us to go 00:02:29.599 --> 00:02:36.560 find some victims so this is our selection of random pci 00:02:34.560 --> 00:02:42.080 express cards that are of sort of dubious value 00:02:39.519 --> 00:02:45.200 uh these actually got for free in scrapyard wars you know what let's start 00:02:44.080 --> 00:02:48.480 with these okay so uh 00:02:48.840 --> 00:02:55.519 oh yeah before we do this i should 00:02:51.840 --> 00:02:57.519 probably enable hot swap 00:02:55.519 --> 00:03:00.239 ah there it is 00:03:01.840 --> 00:03:05.840 no idea what any of these settings do 00:03:05.920 --> 00:03:13.599 sure looks good to me 00:03:10.400 --> 00:03:15.200 i wonder what's better black slots or 00:03:13.599 --> 00:03:22.090 gray slots i'm gonna try a gray slot 00:03:18.800 --> 00:03:25.189 oh this feels so wrong 00:03:25.440 --> 00:03:27.760 okay 00:03:28.959 --> 00:03:36.640 nothing catastrophic appears to have happened 00:03:33.599 --> 00:03:38.799 okay it's not showing up 00:03:36.640 --> 00:03:43.599 let's try a restart stop code driver power state failure 00:03:42.319 --> 00:03:49.519 go ahead and cut okay so one of three things happened here either you have to actually power 00:03:47.760 --> 00:03:52.799 off for it to be detected we're gonna try that first 00:03:51.519 --> 00:03:57.840 or we killed it or 00:03:55.599 --> 00:04:02.080 it was dead already which is quite possible this has been sitting on a 00:03:59.439 --> 00:04:06.080 shelf for literally years either way it can go over there now 00:04:04.799 --> 00:04:09.519 all right now this 00:04:07.920 --> 00:04:13.560 i am at least 40 percent sure works 00:04:14.000 --> 00:04:20.400 okay whoa now hold on a minute 00:04:18.560 --> 00:04:24.160 whoa hold on a minute i think that's more usb than we had 00:04:22.240 --> 00:04:28.960 before okay don't cut this clip because no one's 00:04:27.600 --> 00:04:32.000 gonna believe me if we cut this clip 00:04:37.840 --> 00:04:46.400 maybe i was wrong go ahead and cut so after powering down 00:04:44.080 --> 00:04:50.080 and turning it back on it's working 00:04:48.000 --> 00:04:56.120 did it not show up because the system had never seen this 00:04:52.720 --> 00:04:56.120 device before 00:05:00.320 --> 00:05:07.919 oh oh oh ouch oh uncorrectable error ouch go ahead and 00:05:05.440 --> 00:05:09.920 cut we're gonna disable it then 00:05:08.880 --> 00:05:12.880 we're gonna pull it 00:05:12.880 --> 00:05:17.520 we hot unplugged something 00:05:15.919 --> 00:05:20.639 am i gonna get away with a hardware changes scan 00:05:18.960 --> 00:05:23.360 i'm starting to wonder if these are just bugged on this computer 00:05:22.479 --> 00:05:28.560 look it's still in there but i know for a fact 00:05:26.400 --> 00:05:32.800 see i can prove that the hardware is not in there 00:05:29.919 --> 00:05:32.800 let's just go for it 00:05:34.320 --> 00:05:41.520 oh damn it go ahead and cut 00:05:38.960 --> 00:05:46.840 i'm gonna grab a different boot drive go ahead 00:05:43.039 --> 00:05:52.639 all right let's try a more fresh Windows 00:05:52.639 --> 00:05:56.720 enable oh there it goes 00:05:56.720 --> 00:06:03.039 go ahead and cut maybe the black slots are bad luck 00:06:00.240 --> 00:06:05.840 you let me down buddy go ahead and cut 00:06:04.240 --> 00:06:11.120 maybe we just need to try something that's not a storage device how about 00:06:08.240 --> 00:06:11.120 this network card 00:06:11.680 --> 00:06:16.800 go ahead and cut so what we think we know so far is that we haven't actually 00:06:15.440 --> 00:06:23.000 killed any of the hardware we've been experimenting with i did find a couple potential 00:06:20.160 --> 00:06:27.440 sacrificial cards here so this is like a 5450 00:06:24.639 --> 00:06:30.540 and then this is that titan that we brutally 00:06:29.039 --> 00:06:34.910 savaged 00:06:35.280 --> 00:06:41.840 so the AMD card seems to have given zero f's 00:06:39.440 --> 00:06:46.840 just like the network card um go ahead and cut this is like an og 00:06:44.319 --> 00:06:51.840 titan it's not it's not very high end anymore neither of them are showing up 00:06:49.759 --> 00:06:59.599 let's try a restart here oh my god is that Windows up i hate it 00:06:59.599 --> 00:07:05.919 go ahead and cut okay so we're having problems booting at all go ahead and cut good cut go ahead 00:07:05.120 --> 00:07:10.800 and cut holy sh no oh my what the 00:07:09.039 --> 00:07:16.599 don't prompt again no 00:07:12.080 --> 00:07:16.599 so the AMD card is showing up now 00:07:19.840 --> 00:07:27.840 i think what we have to do is try some more modern hardware 00:07:24.880 --> 00:07:33.260 a 750 series SSD and let's try a more modern graphics 00:07:29.919 --> 00:07:34.720 card a 1050 ti 00:07:34.720 --> 00:07:38.319 oh fans turned on 00:07:38.319 --> 00:07:43.280 that one's definitely getting power 00:07:41.520 --> 00:07:45.360 come on really 00:07:45.360 --> 00:07:48.880 has to be a driver thing 00:07:51.919 --> 00:07:58.639 so let's see if at least after just a soft reset 00:07:57.199 --> 00:08:02.800 they show up because that will tell us if maybe 00:08:00.639 --> 00:08:08.230 Windows is the issue wait what 00:08:05.280 --> 00:08:11.739 the graphics card's not showing up 00:08:12.720 --> 00:08:17.360 let's pull the SSD 00:08:17.360 --> 00:08:19.680 off 00:08:20.800 --> 00:08:26.800 let's fire up Windows server go ahead and cut 00:08:24.319 --> 00:08:31.199 okay okay bye uh so i'm an idiot um 00:08:29.360 --> 00:08:36.159 you don't have to enable this i didn't even read it this just says you have to 00:08:33.120 --> 00:08:38.839 enable this if your os does not support 00:08:36.159 --> 00:08:43.130 pci express hot plug ahead and cut 00:08:41.039 --> 00:08:46.620 so let's go straight for gold 00:08:46.720 --> 00:08:53.719 no here goes the usb drive nope network 00:08:54.480 --> 00:08:58.320 can Linux handle it better 00:08:58.480 --> 00:09:03.519 it showed up and then it crashed 00:09:02.320 --> 00:09:10.000 while we were trying Linux i was preparing a server 00:09:05.600 --> 00:09:12.480 2016 installation oh shut up 00:09:10.000 --> 00:09:16.760 best case scenario so we have the presence of mind to disable it before we 00:09:14.560 --> 00:09:19.880 pull it 00:09:21.120 --> 00:09:27.760 maybe there's some options or something go ahead and cut 00:09:25.600 --> 00:09:32.720 okay so we've reached the point in this project where it's time to talk to tech 00:09:29.519 --> 00:09:32.720 support um 00:09:33.040 --> 00:09:40.800 and i did find a really interesting article so this is an Intel white paper 00:09:37.440 --> 00:09:42.240 about their data center ssds but as you 00:09:40.800 --> 00:09:47.040 guys might have noticed when we were booted into ubuntu 00:09:44.959 --> 00:09:53.040 this SSD shows up as one of their data center ssds they're actually based on a 00:09:50.160 --> 00:09:56.959 very very similar platform in fact i believe they use the same pcb even so i 00:09:55.360 --> 00:10:02.560 was really hoping that this would behave similarly and they do support hot swap 00:10:00.399 --> 00:10:07.040 PCIe including surprise hot add or hot remove 00:10:05.920 --> 00:10:12.080 but native os hot plug no 00:10:10.240 --> 00:10:16.000 so we need to have that off 00:10:15.200 --> 00:10:20.880 okay BIOS hot plug support is only for if it 00:10:18.800 --> 00:10:26.800 doesn't support it natively which this says Windows does 00:10:23.920 --> 00:10:33.360 and we have to ensure that surprise hot plug registers are set correctly 00:10:29.839 --> 00:10:35.839 so i'm gonna try this 00:10:33.360 --> 00:10:40.160 while i wait for ASUS to get back to me go ahead and cut 00:10:37.120 --> 00:10:40.160 oh no 00:10:40.240 --> 00:10:43.120 go away 00:10:44.640 --> 00:10:49.440 all right well i guess if it never detects it it can never 00:10:48.399 --> 00:10:54.240 crash go ahead and cut i think i've been going about this all 00:10:52.240 --> 00:10:59.120 wrong i saw 00:10:55.760 --> 00:11:00.959 pci express hot plug in the BIOS 00:10:59.120 --> 00:11:05.839 and i went yeah 00:11:02.240 --> 00:11:09.680 heck yeah these slots 00:11:05.839 --> 00:11:14.399 but what if what if they actually mean 00:11:09.680 --> 00:11:16.640 pci express storage over u.2 00:11:14.399 --> 00:11:21.920 so this board is actually really unique come have a look at this in that it has 00:11:19.440 --> 00:11:29.519 four this is part of what it's using all those PCIe lanes on the CPU for it has 00:11:25.279 --> 00:11:32.720 four u.2 connectors so these 00:11:29.519 --> 00:11:34.959 are technically 4x PCIe slots 00:11:32.720 --> 00:11:39.760 effectively you can actually just run a cable off of them 00:11:36.399 --> 00:11:41.839 and plug them into a 16x slot 00:11:39.760 --> 00:11:46.800 what they're intended for though are NVMe drives like this one this is the 00:11:44.720 --> 00:11:52.079 same drive as this it's just that instead of this it's got this 00:11:49.519 --> 00:11:55.680 so the board might only be set up for that 00:11:52.959 --> 00:12:00.959 on these lanes i mean it's less dramatic looking but 00:11:58.320 --> 00:12:03.600 this is still potentially really cool which means 00:12:09.040 --> 00:12:17.200 go ahead and cut so i am not defeated 00:12:13.360 --> 00:12:20.480 our wonderful contacted ASUS gary 00:12:17.200 --> 00:12:23.440 has actually worked over the weekend it 00:12:20.480 --> 00:12:27.279 turns out the features there on the board 00:12:24.399 --> 00:12:32.079 and it's exposed in the BIOS it's not enabled 00:12:29.200 --> 00:12:37.760 so they have provided me with a beta BIOS that should enable it 00:12:34.959 --> 00:12:41.839 i actually wasn't that far off the board is only 00:12:39.440 --> 00:12:46.320 specifically designed to support this hot plug functionality 00:12:44.240 --> 00:12:51.519 on the u.2 ports so theoretically when i flash this BIOS 00:12:49.200 --> 00:12:54.240 it will enable or unlock that functionality 00:12:54.720 --> 00:12:59.839 close up 00:12:58.320 --> 00:13:04.480 update time this is weird it dropped me right into 00:13:01.839 --> 00:13:07.839 the BIOS which means i don't know what's going on 00:13:10.320 --> 00:13:15.680 even a SATA drive isn't showing up as bootable in here so like 00:13:16.240 --> 00:13:21.920 there it is can't boot to it 00:13:20.079 --> 00:13:24.320 it's not even beta BIOS it's like alpha BIOS 00:13:26.639 --> 00:13:32.440 okay you can cut i sent ASUS a complaining thing about 00:13:30.000 --> 00:13:38.000 not being able to boot and i got back 00:13:35.440 --> 00:13:42.959 did you rtfm they sent me instructions for a bunch of 00:13:40.240 --> 00:13:46.360 bio stuff to reconfigure in order to enable it 00:13:48.240 --> 00:13:53.519 we're gonna do that i mean i thought it was just a BIOS update 00:13:55.760 --> 00:14:01.600 okay so there is some crazy stuff in 00:13:59.040 --> 00:14:07.920 here i'm supposed to go to socket 1 ports 1a to 1d 00:14:04.959 --> 00:14:14.720 and here is where i am 00:14:10.800 --> 00:14:17.760 enabling hot plug and surprise hot plug 00:14:14.720 --> 00:14:21.120 for my u.2 ports 00:14:17.760 --> 00:14:21.120 okay this is great news 00:14:21.839 --> 00:14:24.639 reading the manual 00:14:26.639 --> 00:14:31.920 i want to see this work 00:14:30.399 --> 00:14:35.900 that's interesting go ahead and cut okay this is the raid 00:14:34.000 --> 00:14:37.519 driver we need 00:14:37.519 --> 00:14:42.399 there it is okay where's my drive 00:14:41.199 --> 00:14:48.160 there it is yeah yeah yeah yeah whatever okay 00:14:45.600 --> 00:14:48.160 here it is 00:14:54.720 --> 00:14:58.120 there it is 00:14:59.600 --> 00:15:06.639 but off camera 00:15:03.519 --> 00:15:06.639 i had another idea 00:15:07.760 --> 00:15:14.079 so there's hot plug options in the BIOS for 00:15:11.600 --> 00:15:17.920 other pci express uh slots on this board but ASUS has 00:15:15.680 --> 00:15:22.480 specifically told me that there's like a finished system that uses this board as 00:15:19.760 --> 00:15:27.120 a base that has a special backplane that enables the pci express slots themselves 00:15:25.519 --> 00:15:31.600 to be hot pluggable but that the standalone board doesn't do it so given 00:15:29.120 --> 00:15:35.839 that following their instructions so far has been my best bet i'm going to take 00:15:33.440 --> 00:15:43.680 their word for it but i have something special 00:15:37.199 --> 00:15:45.440 this is a u.2 to pci express adapter 00:15:43.680 --> 00:15:52.519 so what i'm going to do is i'm going to take what is effectively 00:15:47.360 --> 00:15:52.519 again a pci express slot 00:15:54.079 --> 00:16:01.519 and i want to hot plug it 00:15:57.839 --> 00:16:01.519 i don't know if this is going to work 00:16:03.120 --> 00:16:08.519 oh no dice why don't we try this one 00:16:10.720 --> 00:16:15.920 okay now oh 00:16:16.880 --> 00:16:24.160 you know what no how far has listening to manufacturer 00:16:21.360 --> 00:16:28.800 instructions ever gotten anyone so 00:16:26.079 --> 00:16:33.120 we're going to change not just ports 1a to 1d 00:16:29.920 --> 00:16:37.360 we're going to change all of the ports 00:16:33.120 --> 00:16:40.079 to surprise hot plug and hot plug 00:16:37.360 --> 00:16:42.639 and we are just going to yolo it and see what happens 00:16:43.199 --> 00:16:50.079 one last hurrah 00:16:47.839 --> 00:16:55.199 so something i don't know is if turning on hot plug on the slots could have some 00:16:52.959 --> 00:17:00.320 kind of adverse effect on some other functionality 00:16:58.399 --> 00:17:06.400 so first things first this is my best bet for hot pluggable 00:17:03.600 --> 00:17:11.600 just sanity check i want to try off the u.2 again 00:17:08.480 --> 00:17:14.079 see it's powered though see this is what 00:17:11.600 --> 00:17:19.679 this is what's whoa 00:17:19.679 --> 00:17:22.559 it's it's on 00:17:24.319 --> 00:17:30.400 it works oh it really works check it out check it 00:17:28.799 --> 00:17:36.799 out activity led it's fast even writing 00:17:34.640 --> 00:17:40.240 crazy now i want to push my luck 00:17:45.360 --> 00:17:47.840 oh 00:17:48.400 --> 00:17:54.720 it handled it gracefully the craziest thing is i didn't even have 00:17:52.880 --> 00:17:58.000 to like refresh device manager it was just like it was like plugging in a usb 00:17:56.480 --> 00:18:03.600 device so now we're gonna try the network card 00:18:03.600 --> 00:18:09.920 usb card maybe 00:18:11.360 --> 00:18:16.400 do you see that right there 00:18:16.480 --> 00:18:22.160 no okay hold on hold on 00:18:20.559 --> 00:18:24.880 usb stick check this out
