Hans I'm using aha-2940uw adapter on my DS10. You need to add the following lines to SYS$SYSTEM:SYS$USER_CONFIG.DAT: --- cut here --- device = "Adaptec AHA-2940UW" name = PK driver = sys$pkadriver.exe adapter = PCI id = 0x81789004 boot_class = DK boot_flags = HW_CTRL_LTR, UNIT_0 flags = SCSI, PORT, BOOT end_device --- cut here --- Also I have patched OVMS 8.4 CD which supports this adapter.
