Running kgpe-d16 on testing. Coreboot recognize only the main card to boot Trying Linux distro soon
EDIT: for the gpu I have found the issue
PCIe GPU Output
To use a PCIe GPU as the bootup display, PCIe Option ROMs must be executed by SeaBIOS. This is enabled in 15h.org release ROMs with the âVGA-OpROMsâ tag. The relevant coreboot-15h menuconfig option for SeaBIOS is âPayload > Execute PCIe Option ROMsâ. The âVGA Onlyâ option is the recommended setting when using a PCIe GPU as the bootup display.
But I have download this rom âSeaBIOS + uCode + VGA-OpROMsâ, is the pci-gpu option not already enabled?
Now Opteron reach 75° and shutdown The passive cooling is not possible with this machine. I have to found some decent coolers
Actually I use those âcoolerâ
But donât work (and the case is open, i cannot immagine what happen with closed case), the cpu goes very hot in 5 minutes and the machine shutdown (is a security measure to avoid damage).
Slackware 15.0. Time boot is really fast, about 10-15 seconds after pressing power button the system start I can see the âsgabios bannerâ but no grub
NO..i think is not that. I made some experiments. With coreboot and no active fan the system became in the acceptable range of 60-80°C (60 idle 80 and over under heavy load)
with gnu-boot the temp1 (SR5690) became very hot even without heavy load and today I had os shutdown automatically (is a âdefenceâ of pc when became cpu too hot to avoid damage), is a bug of gnuboot? I use rc6 (latest)
I prefer to use gnuboot because with coreboot a lot of stuff donât work (no ipmi, no serial, and even pc leds donât work).
I confirm. Kgpe-d16 with gnu-boot is a great project. The bad things are:
cooling! Personally I ever use amd product since 2003 because I ever hate Intel (too expensive, too unsafe (but amd with psp is also unsafe) but I never saw a hot cpu like the Opteron. The other bad things for cooling is that is near impossible to found good coolers for g34 sockets
With the modern amd stuff is possible a passive cooling and even with 90° the pc donât turn off
using a passive cooler with Ryzen 3200 maintain pc cooled at 40° in idle and 90° with very very high stress. The problem of modern stuff is the psp for amd and me for intel which are pratically backdoors (they have put stuff into the cpu, there is no way to escape, but seems Intel ME is possible to deactivate). And another bad thing is the proprietary firmwares needed for all (network, gpu, etc.)
Of course money solve all, letâs see this great project. Is cooled with liquid. The price is also good imho. not too high
I spended 9K on Blackbird-Power9 as i have Libre Arctic GPU and 256RAM, plus 2TB nvme, and some others fancy gpus and things. Let me tell you something, i am not interested on money, i am interested in how happy power9 makes me. = )
I do not want x86 ever again, except Librem 14 if it is fully Libre.
Other interesting news, I still donât trust coreboot because it accept the use of blobs (which mean closed components which can hide anything, including backdoors) but is still better than proprietary bios (100% closed 100% not viable imho)
Offtopic: very nice funny error on duckduckgo searching amd epyc
Trying Linux distro soon
