Re: [gentoo-dev] Gentoo installation modifications for 3ware cards

[Tucker I Sylvestro]

Nope, I didn't type modprobe 3w-xxxx until after I built and copied it in
the way I mentioned in the howto.  Nor did I know I needed to probe the
scsi driver in order to have sda created.  That sounds much easier than
then the process I went through ;)

I do think it would be nice to have that linked somewhere off the install
page, or at least somewhere in the docs.  I thought I'd been pretty
thorough about looking in all the right places before trying to roll my
own solution, and didn't find that described anywhere.

Purely out of curiousity, why don't I need to run modprobe now that my
computer's booting off the RAID array?  I compiled the module into my
kernel, so how is it different from the kernel on the CD (which did not
automatically recognize the drives) if the drivers were compiled into that
too?  I'm pretty sure I do have the 1.1a version since I bought it from
Edmunds Enterprises, straight off the link on the gentoo.org home page.

Thanks for the reply,
Tucker
