you don't have a copy of the vga binary then you will either need to rip it out of the fuctory bios image or boot under fuctory and then copy it from memory. The wiki has info on doing this.
Then you can test the bios on the target under the emulator. If it
How? The whole bios? or the vgabios.bin only.
I get this rare output (describe before), if I try to start testbios with the vgabios only. Means, the extracted vgabios only :D
