Concerning the A2091 Controller Card. If I remember correctly the Ver 6.6 RoMs had problems with drives greater than 1.2 GB. The Rev. 7.0 ROMs should be OK though. Ir even better the Rev 6.6 GURU ROM for A2091 if you can still find then.
I have tested 4.2 GB HDD's with the GURU ROM and they are detected properly.
