Home Page Forums MAME MAME anyone ever get an IBM XT/AT working in mess?

That's interesting - HIMEM.SYS doesn't use protected mode that I'm aware of so it should work. Are we not emulating the A20 gate?

Well, A20 is a 286 feature and that's an 8088 driver so....

in the ibm5170 driver the a20 line should be driven correctly by the system board keyboard controller.

What was the keyboard problem?

I am struggling with the hard disk chd file.
I can't get fdisk to on the drive in the emulation, when I type fdisk, the cursor just drops down one line and blinks at me...

One likely possibility for the keyboard problem is that the driver has a .cfg file from back before the keytronic keyboard had its dipswitch set to the correct default. try deleting /cfg/ibm5160.cfg and try again with latest svn or latest release.

I don't have a keyboard problem myself I was just curious.
I can't run fdisk to setup the hard disk, that's my problem... :-)

Sorry for my delay in getting back to people;

HIMEM.SYS was on the DOS startup floppy that I'm using. Not on purpose, just needed a command prompt on the machine to run fdisk.

As for the keyboard problem, it happened from time to time, but I found cleaning out the cfg files helped fix this most of the time.

As for the chd issues (Barry...) I never got it to work. After trying unsuccessfully to fdisk virtual drives I gave up, as it's been reported that MESS has problems with hard drive emulation for the IBM pcs. FDISK would run, create a partition, but upon reboot nothing stuck - back to square one. FDISK would also crash back to a prompt from time to time as well. Barry, if you ever get it working, i'd love to know!
