To start using the emulator, place the ROMs in the ROM directory (I'm using the Turbo XT BIOS as BIOSROM.bin, IBM VGA BIOS as OPTROM.1 and XT-IDE BIOS as OPTROM.2.
Create if needed and mount a hard disk image if you want hard disk emulation. Then:
Place the latest XT-IDE files in a floppy disk image, boot it using a MS-DOS floppy and run the XTIDECFG.EXE. Load the idext.bin image. Go to the configuration menu and select autodetect. Then go to the boot setting menu and set the default boot disk to 0(This will prevent it from trying to boot the hard disk, which isn't working atm). Go back to the main menu and select flashing the BIOS. Make sure that it's set to the correct chip (it's the chip listed in my earlier post, the numbers only (four numbers, NOT the mod version!). Set the Data Write Prevention option to Disabled to allow the ROM to be flashed and start the flashing. After flashing, it should request to reboot, press enter/escape to reboot. When the BIOS loads, it should leave the detected harddrives empty(So it will say something like this:
Master at 1F0:
Slave at 1F0*:
Master at 170: not found**
Slave at 170: not found**
* no not found when two harddisks mounted only.
** These are the CDROM drives. They report as not found when not inserted.
).
If no harddrives are mounted, the CDROM will be at the Primary ATA port(1F0) instead of the Secondary ATA(170).
