emulator advances 's->dsp' index to read next opcode. This can lead

Apparently the bisection result from comment #1 comes from a different
issue, the VGA display stays blank, can not test the floppy drive.
Bisecting using the pcbios.bin from fd646122418~, the VGA display stops
working at:
345c22aa80d1f6ddfe7898f721fd1be3bccb08f1 is the first bad commit
commit 345
So finally, the commit that introduced this regression is not directly
related to QEMU:

[cross posting QEMU & SeaBIOS]
Hello,
I'v been looking at a QEMU bug report [1] which bisection resulted in a
SeaBIOS commit:

For example in qemu 1.5 the nic roms got EFI support and there is a
compat property which switches the pc-i440fx-1.4 (and older) machine

Note that roms with a pci firmware standard
Current parameter was always one. We continue with that value for now
