abit-aw9d raid5 with ICH7R
I'm running into a boot problem configuring a softraid raid5 setup with suse 10.2 using the abit aw9d motherboard. For those unfamiliar with the board, here are the specs:
4 SATA 3Gbps Ports - Intel ICH7R
3 SATA 3Gbps Ports - Silicon Image 3132
1 e-SATA 3Gbps Port - Silicon Image 3132
The problem is that I have 5 identical drives, so I must span two controllers. I'm currently thinking of just doing 1 drive on the sil3132, and the 4 other drives in raid-5 on the ICH7R. The goal is to step the root on the 1 harddrive and store data on the raid 5.
My installer sees all these drives as drive 1-5. However, when configuring the above, I get a grub boot error: error 21.
Grub Loading Stage 1.5
Grub Loading please wait....
So it appears that the sil3132 drive isn't detected in the bios (since that's where grub is looking). What's my options here? Is there anyway I can get the bios to detect it? It seems like the only drives that come up on the 'boot from harddrive' option are the 4 installed on the ICH7R.
Any workaround to this? What the experts suggest?
