Hi all,
First, thanks to all who have answered. The info has been helpful.
OK, after a bit of work putting in a new power supply I now have my
oldest Gentoo machine set up with 3 disk drives. The second and third
drives used to be in the old Windows machine. All drives are masters
on their own EIDE cables.
Drive 1 - Via chipset - Gentoo
Drive 2 - Promise PCI EIDE ATA-100 cont. - port 1 - GigaStudio audio Files
Drive 3 - Promise PCI EIDE ATA-100 cont. - port 2 - Win XP
Note that I have not actually installed Win XP here. I just took the
drive from the old machine. That machine was a Via chipset and so is
this one. First step would be to see if it works then load Win XP from
scratch if it doesn't. (Or load Win XP anyway...we'll see.)
All drives are visible to fdisk and hdparm. I am able to mount
/dev/hdi as my kernel does support VFAT but I cannot mount /dev/hdk as
I do not have NTFS support built for this kernel, nor do I want to add
it.

Now, I wanted to try booting the Win XP drive but I hit a road block.
It seems that possibly grub doesn't see any of the drives on the
Promise ATA-100 controller? Is this the case. grub auto-completion
tells me that only hd0 is available. What limits grub to 8 devices?
(My guess is system BIOS but it's just a guess.)
godzilla ~ # grub
Probing devices to guess BIOS drives. This may take a long time.
GNU GRUB version 0.96 (640K lower / 3072K upper memory)
[ Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists the possible
completions of a device/filename. ]
grub> root
Possible commands are: root rootnoverify
grub> root (hd0,
Possible partitions are:
Partition num: 0, Filesystem type is ext2fs, partition type 0x83
Partition num: 2, Filesystem type unknown, partition type 0x82
Partition num: 3, Filesystem type is ext2fs, partition type 0x83
Partition num: 4, Filesystem type is ext2fs, partition type 0x83
Partition num: 5, Filesystem type is ext2fs, partition type 0x83
grub> root (hd1
grub> root (hd2
grub> root (hd3
grub> root (hd4
grub> root (hd5
grub> root (hd6
grub> root (hd7
grub> root (hd8
Error 12: Invalid device requested
grub> root (hd8
Is grub not able to see drives sitting on EDIE controllers sitting on
the PCI bus, or is there some sort of compile time option / patch I
might need?
If not I could reconfigure the internal cables to share the new drive,
at least the Win XP drive, on the chipset cables, but I'd prefer not
to do that it possible.
Thanks in advance for your ideas.
Cheers,
Mark
