- And under 386bsd, you would use "dd".
-
- As in: "dd if=/386bsd of=/dev/rwd0c obs=8192 count=1" %%
-
- That ought to pretty much blow away the first track or so...
-
- Much simpler than having to go in and actually *touch* code that
- mucks about with BIOS calls.

- %% if you have something other than the start of the hard disk at
- the beginning of the c partition (like you are running with dos
- co-existing on the same hard drive), this will not work for you, I
- think.
