Turns out that it was boot prom (rev. 1.6 from the MD banner), and the earliest version that supports the WD controller is 3 (or maybe 4). Anyway, the current rev is 7, and includes some different PALs, microcode and wiring changes--not just a simple PROM swap. Sigh.... Thanks for all the help from HP/Apollo R&D! Michael Lampi
