More importantly the 2090 won't handle more than 256MB, without using
patched firmware (also, it's SCSI/MFM, it's fairly likely to be a stock
20MB MFM disk, the way to tell is open the machine and look at the
cables, if there's one 50 pin one it's scsi, if it's 20 and 34 pin
cables, it's MFM, you'll need to know a bit about the drive later on
anyway.)

probably works, but... I've used one of these, and it isn't impossible
to set up using the instructions here
http://peach.mie.utoronto.ca/people/tsangc/a2090-10.guide I never had a
setup disk for it, just a boot disk with hddisk.device on it (I think it
lives in expansion) what you need is the datasheet for the drive you
have fitted, which isn't going to be easy unless it's from a still
living brand like Seagate, and some time to screw about with it.

Important: make copies of the boot disk and setup disk before doing
anything to them, they're the only ones you have.
