Thank you for your reply. To answer your questions:

-Yes, I am using v4.0.2
-I tried all of the cheatcodes in the Tips&Tricks sections with the following results:
boot: knoppix vga=0 - hung on following statement:
Scanning for Harddisk partitions and creating /etc/fstab...
boot: knoppix acpi=off pnpbios=off noapic noapm
same results as above
boot: failsafe debug -b 3 - I was able to get through boot process and startup, but still was not able to see hard drive. The only things present on desktop are CD-ROM, Floppy, KNOPPIX.desktop, and trash.desktop icons. I am able to get the same results by booting with the 'nofstab' cheatcode (without losing all of the other hardware functionality).

-I haven't gotten any error messages at all except for one regarding a sound card driver which I don't think would have any affect on this issue.

Any other suggestions on how I might be able to find and mount the hard drive would be greatly appreciated.

Thanks again!
