Ah that little one; some time after 2.3.5x things changed a bit. Make a
directory /var/shm and add to your /etc/fstab the line:
none /var/shm shm defaults 0 0

Hmm that is good going. What does your onboard controller give with the
same drive?

The 8GB problem goes as follows. In yee oldee days the discs were
specified by Cylinder/Head/Sector - but sense dawned on the face of the
IDE community and they realised that was silly now. So all large drives
(should) return a CHS of 16383/16/63 (about 8GB) which is actually an
indication to the BIOS/OS to ignore the CHS and just use the LBA sector
count. If you do an hdparm -i on the drives you should see a CHS like
that but an LBAsects value which if multiplied by 512 gives you the real
size of the drive.
