Problems installing grub on a 'raid' disk

[fat32]

        Hello,

        I tried to install grub on a mirror disk drived by hardware
raid. The raid is adaptec 7899 + dell options, working with a linux 2.2.18
aacraid drivers v1.0.7, two disks from raid adapters : sda (raid1) sdb
(raid5), no ide, no other scsi perif.

        I first configured some stuffs :

title Linux 2.2.18aac
root (hd0,1)
kernel /boot/kernel.2.2.18aac

        Then I tried a grub-install "(hd0)"  (also fd0) and grub-install
return this error msg :

/dev/sda2 does not have any corresponding BIOS drive.

        Then Grub sayed :

grub> root (hd0)
Error 21: Selected disk does not exist

grub> setup (hd0)
Error 12: Invalid device requested


I don't know if it is really a bug or a misconfiguration but i found
nothing in the docs.


Thanks
