Hi all,

I've had troubles with an old software that run under DOS (with Bochs and QEMU). It refused to execute correctly but worked like a charm under DosBox.

After analysis, it came from some unimplemented functions of VGABios and especially AX=0x1121. Here is a patch that resolves my problem. It also fixes some error when calling AH=09 (character writing) after loading a font of different height.

There might be some mistakes remaining in this patch, I did not test everything.
