- I would like to to take this opportunity, as 386BSD moves toward 0.2, to
- lobby for a change in the 386BSD bootstrap loading process.
-
- Every commercial version of U*IX manages to live within the constraints of
- the "default" Master Boot Record, e.g. SVRx/386 has a "boot partition" which
- contains an intermediate boot record with the logic to allow for selecting
- a kernel file to execute.
-
- I run OS/2 HPFS, (MS-DOS? Just say no!), therefore 'shutdown -todos' doesn't
- work. (Yes, I *could* "fix" shutdown, but...) I can't use the OS/2 boot
- manager, which wants its own partition to be bootable, and it handles the
- rest; but because 386BSD doesn't conform to the convention, it can't boot
- 386BSD. I suspect users of other boot managers are suffering the same
- problem.
-
- I like 386BSD despite this shortcoming; but I'd really like to get rid of
- the @#$%^& DOS floppy I have to keep around just so that I can switch
- between OS/2 and 386BSD....
