- Better still.. emulate the TOS hard disk driver interface layer on top of a
- generic, device oriented driver fully integrated into MiNT so as to allow
- asynchronous disk transfers etc.. that would speed up MiNT no end!!
-
- It would also allow MiNT processes to forget what the BIOS thinks is out
- there on the SCSI/ACSI/IDE busses and be able to do it yourself. Maybe then
- we'd be able to have even more esoteric filesystems than the Minix one.

- Hmm.. I hate kludges to get around bugs in other kludged software.
