The 1.7.0 version of SeaBIOS has now been released. For more information on the release, please see:
New in this release:
* Many enhancements to VGA BIOS code - it should now be feature complete with LGPL vgabios. * Support for virtio-scsi. * Improved USB drive (usb-msc) support. * Several USB controller bug fixes and improvements. * Runtime ACPI AML PCI hotplug construction. * Support for running on i386 and i486 CPUs. * Enhancements to PCI init when running on emulators. * Several bug fixes

Great! :) Nice to see a new release out. Please make a notice about the release on the front page of the seabios website.

AFIAK, "==" operator is a bash(?) extension, standard POSIX shell only mentions "=" operator. Changing this "==" to "=" makes it buildable.

This is something which prompted me to test the new release, but it gives... interesting results.
WinXP guest is unable to find drivers for the video adaptor with -vga std and this vgabios.bin, not even its "standard VGA" fallback driver. The device in question is detected as "Other devices / Video controller (VGA compat.)", and its identification looks like:
PCI\VEN_1234&DEV_1111&SUBSYS_11001AF4&REV_00\3&13C0B0C5&0&10
This appears to be bogus somehow, no?

It seems to work okay for me. What did you select in Kconfig, where did you put the resulting out/vgabios.bin file, and what emulator are you using?
Also, if using qemu/kvm add "-chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios" to the command line and post the resulting debug log.

Kconfig was all defaults except VGA ROM pieces (which are off by default). I selected VGA_STANDARD_VGA, VGA_VBE, VGA_PCI and left OVERRIDE_PCI_ID UNselected, since I didn't know what to put there. Maybe the last item was my mistake.
The binaries were put into right place where qemu-kvm picked them -- -bios /path/to/seabios/git/out/bios.bin, and vgabios.bin into the standard qemu-kvm directory, as vgabios-stdvga.bin. I think I learned where to put this stuff by now, after maintaining Debian package of qemu-kvm for over 2 years... ;)
This is qemu-kvm 1.0, I haven't tried with current qemu git version.
Also, if using qemu/kvm add "-chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios" to the command line and post the resulting debug log.

The identification is the same as with seabios-1.6.2 and vgabios-0.6<someting> - the "other vgabios" from bochs project.
I just tried to re-install the video driver in 1.6.2 & 0.6, by deleting the device in device manager and rebooting the virtual machine - and it is unable to find any drivers too, saying this is some "Other device - vga compatible", -- i.e. exactly as with 1.7 and vgarom from it.
The only difference is that with 1.6.2 & vgabios, even if the device is listed as "other device", there are a ton of various video modes available, while with 1.7 & vga rom from it, only one mode -- 640x480, 16 colors -- is available.
This appears to be bogus somehow, no?
Bogus or not, but it was the same with bochs vgabios.. :)
Thank you!

Select VGA_BOCHS in Kconfig for the qemu "standard" vga. The "standard vga" option in seabios kconfig is for emulating old IBM 128K vga cards (ie, not super vga) - I suppose this is a bit misleading.

Oh. Indeed, VGA_BOCHS works, and it is _very_ similar to how vgabios from bochs project works.
And indeed, this is quite a bit confusing. The menut text is also a bit interesting, -- "Bochs DISPI interface VGA BIOS" (what is "DISPI" ?).
Maybe this Standard VGA should be named something like Old VGA?
Testing further....

The "DISPI" refers to the custom protocol that is used to transmit VBE requests between the vga bios and bochs (and is also implemented in qemu). Unfortunately, there aren't well recognized names for these interfaces. I'm open to changing the Kconfig descriptions if there are better names.

FWIW, the first VGA was for the PS/2 and had 256K of VRAM. "IBM VGA" is probably good enough...

Hi,

You'll need to build multiple times with different configurations to get the pci ids right for the various vga variants emulated by qemu. I'll have some build scripts to do that here, just need to rebase and polish them, I'll post the bits ASAP.

Not just a bash extension, as ksh and zsh have it too, but you are right that dash doesn't implement it because POSIX 2008 (Issue 7) doesn't require '==', just '='. [There is a good chance that the next POSIX revision (Issue 8) will require '==' as a synonym for '=', but as that version of POSIX is still several years away, you're still better off sticking to '=' for now.]

It's easy enough to fix in SeaBIOS (for the next release).

Um, this should be done by replacing a "choice" in the config with multiple booleans, so it builds several vgabios binaries.
I thought about implementing this the very moment I tried to build my first seabios with vgabios enabled, but was distracted by something else and now you say you already have something almost ready... ;)
Anyway, I can confirm that seaVGAbios works quite well so far, except the usual issue with Linux VESA driver (which present with bochs vgabios too). So using seabios for all this stuff appears to be a good idea.
Thank you all for the great work!
