IDE on GVP A3001 Accelerator

[DamageX]

I have the same setup, 50MHz GVP A3001 and GVP HC+8

I have an 80MB IDE drive that was originally included with the A3001 but that is the ONLY drive that seemed to work with it. I tried some larger (400MB-2.5GB) WD, Seagate, and Quantum drives without success. So I disabled the IDE and use a 2GB drive attached to the HC+8 instead, it's faster anyway.

I think you should leave the RAM installed in the HC+8 since it can't hurt anything. The 32-bit RAM should take priority for applications (maybe with older kickstarts you have to set it manually but I've only used 3.1) and I think that if you have everything configured correctly then the RAM on the HC+8 can be used for buffers which saves some 32bit RAM and also allows for the fastest possible DMA speed.

Whether or not the A3001's RAM is outside the ZorroII address space depends on which RAM board you have (IIRC). I have 12MB of 32bit RAM and it is (naturally) outside the ZorroII space so it can't be accessed by the HC+8

On my system (I have 4MB installed in the HC+8, and I have FFS with 2KB blocks and 160 buffers), diskspeed says it can get up to 3.5MB/s
