Um that depends, the models the OP was discussing IIRC are XT controlers

However for 16 bit AT type controllers you are mostly correct, that they
don't need a BIOS since the AT rom does know about hard disks.
There where exceptions however I have (or used to anyways) in my box of
old cards a Seagate (I think) RLL controler that did have onboard bios,
I believe for very old AT type boards that didn't have CMOS settable
drive parameters.

Now, here's the dilemma. The stock card
won't respond to the usual
debug commands - they just freeze the computer. The original 20mb 3 1/2"
Normal MFM controllers never come with an own BIOS, so there's nothing
to jump to.
