I E800 mentioned at the bottom of the main AutoSCSI screen near the bottom. I also see it when I choose "Select Adapter". My card may be newer....

My motherboard insists on autoconfiging the card :) (nice to have PCI that works!). > I tried booting with -c and setting the I/O port to e800, but the > kernel always reports `bt0 not found at e800'.
