The current 2090 firmware (in the ROM for the Z80 onboard) only
supports the old St506 standard of 8 heads. Many modern drives support using
one of the now unused lines (I think the reduced write current line) as an
additional head select line. Dale Luck burned a custom version of the
ROM for himself that does this, I'd advise contacting him (amiga!gfxbase!dale,
I think).
