Hmmm... indeed! My bios.bin size is 64KB. I am using the bios coming
with ADLO (bochs/bios/ in ADLO directory)
So I understand that the 64KB bios only provides 16bit BIOS, and the
128KB (which is catted by 16bit (64K) + 32bit (another 64K)) provides
both 16bit & 32bit BIOS?
If that is correct, how to get the 128K BIOS now?
