You boot using the liveCD as usual.

Choose "gentoo doataraid" at the boot prompt.
Or you can just do:

modprobe ataraid
modprobe pdcraid

Now you install as usual using the installation howto.

I have chosen to have /boot on hda. So this howto assumes your doing that too.

this is so that i can install grub on mbr of my hda. So i don't need more then one bootloader to boot different OS's.

Also in my BIOS hda boots first.

You compile your kernel with these options:


ATA/IDE/MFM/RLL support --->
<*> ATA/IDE/MFM/RLL support
IDE, ATA and ATAPI Block devices --->
[*] PROMISE PDC202{46|62|65|67|68|69|70} support
[*] Special UDMA Feature
[*] Special FastTrak Feature
<*> Support for IDE Raid controllers (EXPERIMENTAL)
<*> Support Promise software RAID (Fasttrak(tm))

Remember to start /boot right from the begining by formating it.
This is so that i know its making a clean install and it will have fresh stage's

When install grub, don't do the setup (hd0) etc etc yet. Just emerge
grub and then skip to the section on the howoto about making the
floppy disk.

Now its not a good idea to use an existing one. Create a NEW one
using the commands in the howto.

Then you reboot with the floppy and do:


grub> root (hd0,0) // Your boot partition
grub> setup (hd0)

That should do it.

In grub.conf you should have:


title=Gentoo Linux RAID
root (hd0,0)
kernel /bzImage root=/dev/ataraid/disc0/part1

Thats all you need.


Also have fun.

If anyone thinks i'm talking nonesense here and wants to correct some mistakes please PM me or something.i will correct it.

All i know is that this precedure worked for me.

I have a Giga-Byte 7VRXP motherboard. It has a Promise PDC20276 RAID.

In the kernel it doesn't seem to support it, but when i compile in the module which is meant for PROMISE PDC202{46|62|65|67|68|69|70}
It seems to work.

I used the normal gentoo-sources kernel.

PS: If anyone wants anymore informations about my setting that i haven't mentioned here please let me know.
Athlon XP 2001, Giga-Byte GA-7VRXP MB, 640Mb DDR RAM 333MHz, MSI Geforce 4800SE 128Mb DDR, 40x12x48 Liteon CDRW drive, Flower Cooler, ADSL Router
