That's interesting. When I upgraded to RH7.3 I added a big drive to my 
ancient Iwill xa-100+ based machine using a Maxtor (rebranded Promise 
using PDC20267) ATA-100 card and drives showed up as /dev/hde thru 
/dev/hdh. Worked fine. What DID NOT WORK, however, was my floppy drive. 
That controller stomped all over it, forcing me to justify a CDRW.
