I just updated my A500 in a Checkmate 1500+ case from an A2091 SCSI card with 2 MB (Which was working fine) to my Oktagon 2008 SCSI with 8 MB of ZIP RAM. I have Amiga OS 3.1.4.1 with BestWB installed.
I seem to be getting occasional lockups and reboots with the new card that I was not really seeing on the A2091. Generally when hit the hard wre fairly hard with a graphics program, but sometimes when I do something simple like open a Shell.
I tested the RAM with John Hertell's DiagROM and it seems to pass OK. When it works, it works fine. SCSI is set up with Direct SCSI enabled, Max Transfer set, no long file names, and all partitions < 4 GB (Because my A2091 would not see anything larger, not sure about the Oktagon) Oktagon has version 6.8 of oktagon.device
SCSI Drive is a SCSI2SD with a 64 Gig card, divided into 4 - 4 GB partitions (Because of the A2091 limitations)
Anyone else using the Oktagon with 3.1.4 and had issues? Is it generally not compatible? I tried it for a while under 3.1 and it seemed more stable.
