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.

Bogus or not, but it was the same with bochs vgabios.. :)

Thank you!
