Sorry everyone, I lied. RedHat 8.0 uses kernel 2.4.18-14. My BIOS options that I have tried with my RedHat 8.0 system are:
=09Normal - no response from directio or ppdev =09EPP - response from directio only =09ECP - not tried =09ECP + EPP, DMA mode 1 - no response from directio or ppdev =09ECP + EPP, DMA mode 3 (default) - no response from directio or ppdev > Now, I have tried some of the latest distros as I mentioned (all with > kernel 2.4.19 as you guessed) and cannot get the scanner to work in EPP > only mode. So I have tried your suggestions and switched back to ECP/EP= P > and now I get no response whatsoever.
