[wplug] Grub - Windows Drive arrangements.....

[Vanco, Donald]

I don't think this has anything to do with your bootloader UNLESS you can
control the device order in your machines BIOS.  The drive swap in GRUB
merely insures that the IDE drive is seen as the first hard drive, since
(generally by default) the presence of a SCSI HD device would place SCSI as
"first" in the boot order.  So - you need to insure that you're not
presenting the IDE first in your BIOS and then swapping in GRUB - but my
guess is that you're not given the intelligence built into GRUB at install
time.  It knows pretty well what to do....

As far as drive letters and such - that's pure Windoze crap and you can
change any drive letter to any assignment that you want (with the exception
of "C") as well as hide devices (great to keep Windoze from constantly
asking you to format Linux parts) - but that's a lesson for another
list......

And why in the world do you have a DOS disk in 2 partitions???  Ugh.
