- This is and oldie-but-goodie (FAQ years ago): The universal boot disk
- uses the bios driver to access the hard disk(s). This driver is not
- interrupt driven (or something of the kind), and thus cannot work in
- protected mode. In real mode, Minix cannot access more than 1 MB RAM
- similar to DOS. Apparently your Minix uses a good 200 kB for itself
- leaving you with a pathetic 760 kB for programs.
-
- The solution is easy: recompile Minix with the appropriate driver
- (at_wini.c for you), and reboot.

- Just one suggestion: for such a machine I highly recommend getting
- the Minix-386 patches, giving you a genuine 32-bits machine. For
- the unfaithful, if you're not into OS study, may I recommend Linux,
- since that has much more features than Minix or Minix-386.
