Raidcore hasn’t released drivers that support gentoo linux, only precompiled drivers for the other big distro’s.
I’ve managed to get the drivers for the bc4000 series to work on Gentoo Linux 2006.0 on linux-2.6.16-gentoo-r9 for the bc4852 card.
You need the driver SDK, which contains the source of the precompiled drivers they distribute.
I had to tweak some kernel configurations to get it to work — first of I had to turn the ‘sysrq magic key’, although it seems easy to remove all sysrq usage in the drivers itself iif you aren’t comfortable with sysrq.
I had to switch from ‘discontiguous memory’ to ‘sparse memory’ layout — the driver relies on the availability of ‘mem_map’.
In the Makefile of the bcraid there’s an issue with the PLATFORM define. It should be defines with ‘uname -m’ instead — otherwise it won’t link in the binary blob.
The bccfg init script they provide seems terribly useless, adding ‘bccfg’, and ‘bcraid’ for that matter, to /etc/modules.autoload.d/kernel-2.6 does just as fine, but cleaner.
Initially it seems that everything works fine, although I’m a bit worried about a lot of errors related to the bccfg device nodes in dmesg.
