Martin, I tried different kernels: 2.6.25.04-fd16 Gentoo-based SysRescueCD -- works 2.6.23.17-88.fc7 Fedora 7-i386 install DVD -- works 2.6.23.1-21.fc7 the XS-163 CD -- kernel panic 2.6.21-1.3194.fc7 Fedora 7-i386 install DVD alternate kernel -- works However, your suggestion sparked an idea that appears to have solved the problem. Even when I use the Fedora7-i386 vanilla DVD, it uses /dev/mapper/pdc_bbbh as the device instead of /dev/sda. When I was using the "kickstart configurator" it would generate lines like "--clearpart --all --/dev/mapper/pdc_bbbh" instead of the "--clearpart --linux --sda" that you have on your XS-163. So, I took the cover off the machine and unplugged the second drive, so that now there is only a single SATA disk. In this configuration, XS-163 CD (unmodified, straight from the OLPC website) installs just fine. This clears a major hurdle. Apparently having two identical SATA drives was enough for it to think that "software" or "hardware-assisted" RAID would be used, and changes /dev/sda to /dev/mapper/pdc_bbbh. I will now see if "adding a second drive" can be tolerated "post-installation". Thanks Tony Pearson Senior Storage Consultant, IBM System Storage?

The standard F7 install CD has a very early kernel, our install CD has a recent F7 kernel. In short, the recent F7 kernel doesn't like your SATA controller. It's a nasty incompatibility. One alternative is patience + google to find a workaround. Another one is to get a different mobo or SATA controller. cheers, m -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff
