about using them as RAID controllers. Certainly using them dual-boot with
Windows would be an extremely bad idea (something is bound to go wrong). No,
haven't tried, am not going to.

understandable, because HPT37x RAID is essentially a software raid. Or so I
have been led to believe.

which is compatible with your kernel. I wouldn't count on that.
You might want to use the chipset as an IDE controller and construct a
software RAID with the help of Software Raid HOWTO:
I'd say that you'd want to aim at either RAID-1 or 5 (depending on the
amount of disks). If you happen to have four disks, then you could either
construct an array of 4 disks (usable capacity 3) or 3 disks + spare (usable
capacity of 2).
Of course, the problem of how to boot on a raid system crops up; I've used a
setup where there are two large disks coupled together as a raid-1 array and
a small (well, 20 GB) disk where root (/, /boot, /etc, /var, /lib IIRC)
resides. However, the weak point in this kind of setup is that in the event
that the system disk develops an acute problem (such as headcrash) the whole
system goes down (at least if the IDE driver crashes with the disk).
Read RedHats installation doentation and see if it says anything about
supporting software raid.

you ever could do *anything* without a versatile shell.
