SeaBIOS can use VGA on PCIe cards - the problem appears to be that SeaBIOS isn't scanning all the PCI buses on the machine. Try setting extra-pci-roots as described previously. > Any ideas on SeaBIOS not booting from hard disks or USB storage devices? I suspect the problem with USB storage is really just a result of VGA not working and the behavior of third-party bootloaders when a vgabios isn't found. See my previous email. -Kevin

To support this, seabios needs the CBFS file 'etc/extra-pci-roots' to be set - see: http://www.coreboot.org/SeaBIOS#Other_Configuration_items Ideally, one would set this to the number of extra PCI roots (eg, 1 or 2), but it can also be set to 255 to force a scan of every PCI bus (which takes a little longer on each boot). > Here's a simple diagram showing roughly how devices are connected on the > board: http://ibin.co/20n6DtSrgZSv > > Here's the console output (SeaBIOS log level 8): > http://pastebin.com/jKu21dTV > > SeaBIOS also detects USB mass storage and hard disk drives, but can not > boot from them.

I don't see anything wrong in the log - those messages all appear normal. It's not uncommon for bootloaders to get confused when a vgabios isn't present, so I'd track that down first. If you can't get VGA working, consider installing sgabios as described at: http://www.coreboot.org/SeaBIOS#Adding_sgabios_support -Kevin

Sun Ultra 40 M2 - VGA Card Option Rom not detected
by Nick 07 May '15

07 May '15

Hi guys, I just got coreboot with SeaBIOS payload up and running on a previously unsupported system. The system is a Sun Ultra 40 M2 which is very similar to the NVIDIA l1_2pvv development board (which already has a coreboot port.) Coreboot detects the VGA card and outputs the text "found VGA at PCI: 43:00.0", however, SeaBIOS does not seem to be able to detect the VGA card and doesn't seem to enumerate that bus. It would appear that the option rom is not being ran. Here's a simple diagram showing roughly how devices are connected on the board: http://ibin.co/20n6DtSrgZSv Here's the console output (SeaBIOS log level 8): http://pastebin.com/jKu21dTV SeaBIOS also detects USB mass storage and hard disk drives, but can not boot from them. There's a HALT statement and a bunch of errors (also seen in the log file.) The boot device was a USB mass storage device with linux installed and boots successfully with the vendor bios. Thanks in advance! -Nick

Problem with USB keyboard and mouse
by Anteja Vuk Macek 07 May '15

Hi, I'm begin with coreboot and seaBIOS. I have the problem with USB keyboard and mouse. When I boot the firmware my keyboard and mouse don't work. I use : coreboot, payload seaBios, MinnowMax board Problem: What I need to do for correct a firmware?

SeaBIOS not fully working when compiled on FreeBSD
by Roger Pau Monné 01 May '15

01 May '15

Hello, I've compiled SeaBIOS on FreeBSD with gcc48, and although the build process succeeds, the resulting binary doesn't fully work. Most functions seem to work fine but there are some int15h functions that don't work properly (ie: they return invalid values). I've compiled SeaBIOS with CONFIG_DEBUG_LEVEL=10 and got the following output (this is from the Xen console): [...] (d4) enter handle_1a: (d4) a=00000200 b=00000000 c=00001725 d=00003400 ds=4cf0 es=9eb8 ss=dd00 (d4) si=00000004 di=00000000 bp=00000000 sp=0000fe66 cs=0000 ip=9336 f=0242 (d4) enter handle_1a: (d4) a=00000200 b=00000000 c=00001725 d=00003400 ds=4cf0 es=9eb8 ss=dd00 (d4) si=00000004 di=00000000 bp=00000000 sp=0000fe66 cs=0000 ip=9336 f=0242 (d4) enter handle_1a: (d4) a=00000200 b=00000000 c=00001725 d=00003400 ds=4cf0 es=9eb8 (XEN) irq.c:386: Dom4 callback via changed to Direct Vector 0x93 (XEN) irq.c:276: Dom4 PCI link 0 changed 5 -> 0 (XEN) irq.c:276: Dom4 PCI link 1 changed 10 -> 0 (XEN) irq.c:276: Dom4 PCI link 2 changed 11 -> 0 (XEN) irq.c:276: Dom4 PCI link 3 changed 5 -> 0 (d4) enter handle_15: And that's all, there's no line containing the register values. I'm quite lost at figuring what's going on, so any help about how to proceed in order to debug this is highly appreciated. Thanks, Roger.
