I think SetCPU (http://aminet.net/package/util/misc/SetCPU) can be used for that. Just make sure your system does not have any RAM outside the lowest 16MB address space.

I don't think the A-Max cartridge works with 400K or HD Mac drives.

Are you able to confirm your 800K drive works on a real Mac?

I meant which emulated Amiga HD controller is the CF connected to. The default is probably WinUAE's (Windows-)native uaehf.device, which would be like connecting a super-fast SSD to a real Amiga. :)

Set SCSI2SD SCSI ID to 0. Use HDToolbox to set the last unit flag in its RDB. Try using SetBatt (on Aminet) to reduce SCSI selection timeout and disable multiple LUN support.
