AHA1542 - ISA controller with floppy support. AHA1540 - ISA controller with no floppy support. That's it. The 1540 was about as close to a a standard floppy controller in the ISA world as you could get. RH/NetBSD should certainly install on one. Heck, I've installed RH on a 486 with a AHA2840 VLB SCSI controller. Given the weirdness of VLB, that's pretty remarkable.
Mine is a 1542CP, but NetBSD gave me an "probe: aha0 error" and then just stopped booting. As far as RH goes, I'm not surprised. You can install linux on a toaster!
