ata100 in grub

[Insodus]

I have a problem with dual booting my gentoo system. I've tried using grub, but when I do hd(4,0) which is the correct address of my promise ata controller, it doesn't recognise it. Apparently grub doesnt see the card but gentoo does.

Then i tried using the winXP boot loader, using the dd command I tried getting /dev/hda1 bs=512.... but it returned a file with all 0's.

Any ideas how to fix either option?

I think I would get the same problem when I try to install Gentoo on my box.

There are the following components:
* Normal IDE-controller (2 Ports, 4 Disks) but none used.
Simply a CD-ROM is attached to one of the normal IDE-Ports
* ATA100 contoller onboard, first port used with 2 hard disks
second used with one hard disk.
=> There are 3 HDs on the ATA100 controller and none but a CD-ROM on the bios-controlled ports.

The gentoo-Install-CD get's my first harddisk (where I'll try to setup gentoo) as /dev/hde1

So what to put in the grub-configuration?
And what do I have to put there if I want to install grub into /dev/hde2 (or something like that, I don't know yet)

Yes I really do.
4 ports on standard IDE, and 4 on ATA

When linux boots up it says hde: IBM097814 whatever
and since winxp is the only partition on the disk. wouldnt it be (hd4,0)

can you show us your whole GRUB setup (menu.lst or shell command you are using?)

Okay, I found out by trying:

Grub counts only harddisks installed.
My boot-drive is /dev/hde in linux but (hd0) in grub.
so my linux-partition is /dev/hde7 in linux, in grub it is (hd0,6).
