Hi,
Currently we have 2 vgabios: vgabios.bin and vgabios-cirrus.bin. Is
there any difference between them? Does one offer more features than
the other, or what?
I imagine that we have 2 vgabios because some OS prefers one to the
other, but cannot confirm that.
Many thanks,
Jun

Betts @ 2008-05-09 4:49 UTC (permalink / raw) To: qemu-devel I think the reason why we have two VGA BIOSes is because one is for the original, non-cirrus VGA card, while the other one is for the Cirrus card. The latter is used by default on I386. On May 8, 2008, at 8:52 PM, Jun Koi wrote: > Hi, > > Currently we have 2 vgabios: vgabios.bin and vgabios-cirrus.bin. Is > there any difference between them?

But this still doesnt answer my question: what is the difference between these two BIOS, and why I should use one but not the other.

The vgabios.bin is designed for standard VGA with Bochs VBE (8 MB adapter that doesn't exist as real hardware). The vgabios-cirrus.bin should be used for the CL-GD5446 adapter. Qemu uses the Cirrus adapter and it's vgabios by default, unless you use the -std-vga switch. -- Bye Volker ^ permalink raw reply [flat|nested] 4+ messages in thread
