Yes, if you junk the IDE and set the SCSI drive's ID to 0.
The 1540 card's BIOS will do the job... remember to set
your CMOS HD setup to type 0 or No drives fitted.

The 1540 has problems with drives over 1Gb - you need to boot
off an alternative device and load aspi4dos.sys for the SCSI
drive.

Is a 100Mb IDE drive really worth fitting these days? :)
