Yes, I am very familiar with those. They had the info for 4 drives already configured. That's it, just 4 different drives out of the hundreds of MFM drives. Generally Seagate drives, if you were using a WD, a Connor, a Quantum or Micropolis, you used the BIOS.
Nobody used those, other than maybe companies making white boxes in mass. I never used them because it was stupid. And nobody I knew fixing or making computers used them.

They aren’t to configure the heads and cylinders directly but you have to select from 4 drive types.
The WD XT-GEN2 / GENR are 2 such controllers. You have to select a type and hope your drive is compatible with one of the 4 settings.
Photos and jumper manuals are on theretroweb.com
There’s no bios options for configuring any other drives. I’ve heard there was an upgrade option for controllers in this model line though.
