Define 64-bit, and how do you making the declaration that it is not supported.
64-bit data transfers are performed by Hardware and can not be instrumented. Only a PCI trace will know. 64-bit dma addresses is supported, but the card's registers must reside in the 32-bit space regardless (Memory at f0000000 32-bit prefetchable is for the register set, not DMA). The driver does not turn on DAE until there is more than 4G of memory in the system to use the more optimal 32 bit SG elements. 64-bit LBAs are not supported in currently released Firmware.

I'm using aacraid for my adaptec 2200S with a RAID5 configuration, in a PCI-X slot and I've spent two full days now trying to get it to run in 64 bit mode to no avail. I've tried 2.4.29 with stock aacraid as well as 2.6.9 with stock aacraid and also adaptec's aacraid-1.1.5 with 2.6.9. I am also running firmware version 7349 on the 2200S. Here's my lspci output: 02:01.0 RAID bus controller: Adaptec AAC-RAID (rev 01) Subsystem: Adaptec 2200S (Vulcan) Flags: bus master, 66Mhz, slow devsel, latency 32, IRQ 24 Memory at f0000000 (32-bit, prefetchable) [size=64M] Expansion ROM at <unassigned> [disabled] [size=32K] Capabilities: [80] Power Management version 2 The on-board (non-raid) AIC-7902 controller on my SuperMicro P4SC8 motherboard runs in 64-bit mode without a hitch but I really need to use this 2200S... Would anyone mind beating me with the clue stick or pointing me in the right direction? I need throughput!
