- RE: Alternate root file systems
-
- There doesn't seem to be a problem in specifing an alternate root
- file system, and I have inplemented them on a number of SCO UNIX
- machines I have installed. The reason being that it can be much
- easier and faster to get a machine up and running again after a
- crash (or someone being particularly nasty and doing something like
- deleting all the device files and unix) than by using a floppy set.
-
- I do believe that there is a restriction, however, that the root file
- system reside within the first 1024 cylinders of the drive.
-
- I seem to recall the syntax as being as follows
-
- boot: hd(40,X)unix root=hd(40,X) swap=hd(40,1)
-
- if booting from the hard drive, where X is the minor number of the
- alternate root filesystem, and hd(40,1) is the default swap device.
-
- if booting from a floppy, just leave out the hd(40,X)unix part.
-
- Good luck.
-
- BTW...
-
- The only way I was ever able to get OS/2 to co-reside with both SCO
- UNIX and DOS was to install DOS first, then OS/2 in dual boot mode,
- and then SCO. The dual boot mode of OS/2 never worked, so to boot
- UNIX, I would type unix at the boot prompt. To boot to OS/2, I'd
- type dos at the boot prompt. To boot to DOS, I had to boot from a
- floppy
