Two FAQs posted to too many newsgroups...

The Adaptec 2920 is NOT a cheaper version of the 2940. It is a Future
Domain card, and uses the fdomain driver. See the SCSI HOWTO. Some
people are having trouble getting new versions of this card detected.
This is courtesy Adaptec, who probably made some minor change to the
card that breaks the Linux driver. Adaptec used to support Linux, but no
longer does.

The 16MB RAM problem is a "feature" of all Compaq systems. The BIOS call
that Linux uses to get the amount of system RAM normally returns up to
64MB, but on Compaqs, it will return a maximum of 16MB. The new
production kernels will have this fixed (2.2.x or 3.0.x?), but in the
meantime, you have to manually tell Linux the amount of RAM.

At the boot: prompt - mem=32M
In /etc/lilo.conf - append="mem=32M" - Place this under the "Linux"
heading in the file, and re-install lilo by typing "lilo" at the command
prompt.
