Hi Eric, I fixed the issue. As I mentioned before I use a Compact Flash card as a harddisk and I noticed that I could only boot FreeDOS once after that I had to re-insert the CF card (to select ATA mode). The problem turned out to be my BIOS INT13/00 code which, for an unknown reason kills the ATA mode and reverts it back to Card mode. Since the kernel calls this service early on (ReadAllPartitionTables() in initdisk.c) it resulted in the partition error messages and defaulted back to the A drive.
So I am getting close, I just have to sort out the keyboard routine. I tried redirecting command.com to COM1 but this seemed to fail (still tries to read from CON?)
