sdb2 1GB type 0x83 (swap)
Comments/Problems:
When the root filesystem is installed on a RAID1 MD device (without a /boot
partition), by default the installer does not mark the components devices
(let's says sda1 and sdb1) as
bootable in the partition table.
Grub is then successfully installed in the MBR of sda but some really really
stupid BIOS (tested on at least 2 different Intel motherboards) refuse to
consider the disk as bootable
unles at least 1 partition is marked to be bootable. In fact, no matter which
partition is set bootable, the bios just don't try to run the MBR loader if
there is no partition marked
to be bootable.
For the moment, one solution is to boot the installation CD in rescue mode just
after install, run cfdisk in a shell and set the Boot flag on the first
partition of the first drive
(let's say sda1). This solves the problem. reinstalling grub in the MBR is not
mandatory.
It would be VERY useful to add a small warning at Grub installation time
"Warning : The disk where your are atempting to install grub has no bootable
partitions. In this particular
situation, some (uncommon) systems will refuse to run the bootloader even if
it's correctly installed. To avoid this problem, you need to toogle the boot
flag of one partition on the
concerned drive. Would you like to run the partition editor now ? (default
choice=No)

About hardware report and install report.
Sorry but I didn't wrote this bug report on the buggy machine, so the hardware
summary was false.
