[H-GEN] Changing IDE HDD Controller Drama

[De Crow]

Ok guys here's a screwy one for you all.

I have a FileServer with 7 IDE HDDs in it, and one CDROM

Which was:
/dev/hda1 /boot
/dev/hda2 /
/dev/hda3 SWAP
/dev/hda4 /var
/dev/hdb1 DataDrive1
/dev/hdc  CDROM
/dev/hdd1 DataDrive2
/dev/hde1 DataDrive3
/dev/hdf1 DataDrive4
/dev/hdg1 DataDrive5
/dev/hdh1 DataDrive6

/dev/hda /dev/hdb /dev/hdc and /dev/hdd were connected to the onboard IDE
controller.
/dev/hde /dev/hdf /dev/hdg and /dev/hdh were connected to the Adaptec 1200A
IDE RAID controller

Now I've been having some Kernel Panics/random freezes when lots of data is
transferred from drives on the Adaptec controller. So I thought I'd replace
it. So I went out and bought a generic cheap Silicon Image ATA133 RAID
controller, now given that the drives are in single disks I thought I'd have
no problems transplanting them.... well the data is fine and you can access
everything if I boot off a knoppix CD.  However the Debian Sarge that is
installed to "hda" now doesn't boot, now it's not a BIOS problem afaik,
cause it still boots off hda except that it's NOT hda it's hde.

I now have a map that looks like this:
/dev/hda1 DataDrive3
/dev/hdb1 DataDrive4
/dev/hdc1 DataDrive5
/dev/hdd1 DataDrive6
/dev/hde1 /boot
/dev/hde2 /
/dev/hde3 SWAP
/dev/hde4 /var
/dev/hdf1 DataDrive1
/dev/hdg  CDROM
/dev/hdh1 DataDrive2

Any ideas on how to fix this?  BIOS still lists the drives in the same
order, not this new order, so I'm thinking that it's a Linux/GRUB or
something glitch?

Thanks for any help in advance.
