[Server-devel] Problems installing XS on new system for Uruguay

I'll try the "lspci" commands to see what it says.

What "dmesg" should I look for?   -- when I do: dmesg | grep "sd"[ab]  I 
get that it finds both /sda and /sdb individually, so not detecting the 
RAID mode.

The "autoinstall' fails either because of the Radeon X1200 or the 
"clearpart" command on Line 23.  I've burned a copy of XS-160-noauto if 
you want me to try that.

I've been scanning the Fedora forums for "dmraid" support, and it doesn't 
look like it has support for this SB600 SATA RAID controller.

Uruguay = EduBlog/Ceibal/Greg Smith.  I am building the server to Greg's 
request, so whatever he is now calling this project that is what it is.

Nice hw! But the sata controler might not be supported. When you load
F8 64-bit or Ubuntu,

 - what does lspci say about the SATA controller?
 - what kernel module loads for it? (dmesg will name it)

It often complains about graphics cards. Nothing to worry about -
Compiz won't be enabled on the XS ;-)

Recent images are "auto install" so you don't need to run olpc-install
by hand...

Unfortunately, we have a few custom packages that are compiled 32-bit
only (nothing too bad, just a recompile away) - but I think your
problem is with missing drivers in F7. Can you try installing F7

No idea bout AHCI or fakeraid - sorry

Now - one point I'd like to understand better - when you say "for
uruguay" you don't mean the Ceibal team, right? (From OLPC
perspective, if you talk about schoolservers in Uruguay, the Ceibal
team is what I think of...). You are doing this for the Edublog
Uruguay team... yes?
