Replaced batt and reset NV ram as diredted. Bios reports first boot option as CD followed by floppy & HDD.
After power up it runs through SCSI drives and tape etc then reports "no boot device available"
Have swapped CD/Floppy combo drive - green light flashes when CD inseted. Both drives do the same when mounted.
Similarly does not "see" USB drive - BIOS configured correctly and wireless USB mouse works OK.
What am I missing ?
