New Install on CERC/4ch IDE RAID Controller

[MullaXul]

I'm using a 2006.1 minimal live CD, and can't seem to get the boot disk to see my RAID 5 logical drive. It seems to think this is a megaraid card and loads the associated module, but a check with "fdisk -l" results in no devices found. I've seen several older posts about this exact problem, but they refer to using the megaraid driver which is already loaded. The card appears to be made by Adaptec.

This controller has become the unwanted child in the new Megaraid driver: it's now unsupported.

Tracking it in the Debian/Ubuntu world, I've come to the conclusion that 2.6.15 kernel, using the older megraid driver I can boot and work. Firmware 6.61 is considered "working", yet my own testing shows that it doesn't support disks bigger then 128G, truncating bigger units.

Not sure why LSI, which maintains the driver from reading the source code, would remove the CERC aka LSI i4.

What boot cd did you use to make that work? I tried the Gentoo LiveCD 2005.0 which has 2.6.15-gentoo7 as the kernel, but no legacy megaraid driver. It also has firmware 6.62, which hopefully won't break it further. It'd be a shame to have a single 2.4 machine out of all my servers. Thanks for your help.
