Problems installing 8.04.1 alternate amd64 on HP xw6400

[Nate Moore]

I have an HP xw6400 with a TSST TS-H492C CD-RW/DVD-ROM and a Maxtor ATLAS10K5_146SAS hard disk.  When I boot off the Ubuntu 8.04.1 alternate amd64 cd neither devices is recognized.  There is a message about "SRST failed" before the installer interface starts.  I'm stuck at the installation step where the it is looking for the CD-ROM.  I've dropped into a terminal session to check the output of dmesg and as far as I can tell it does not see my optical drive or my hard drive.  Loading the ahci module does not help to see the CD-ROM and I don't believe I'll be able to partition my hard disk as the mptsas module isn't provided (maybe it's built-in?).

I know this system works fine as has been running WindowsXP Professional.

I would appreciate any help.

Thanks!
Nate
