does anybody know a scsi-controller (besides ALF2) that supports: - FULLY functional disconnect/reconnect-protocol - multiple LUNs - password protected partitions - automount of all partitions - autoboot from FFS-partition - RDBs (interchange of media with other controllers like A2091/A3000) - hd_scsicmds - changeable media (syquest) with FFS ??? -- best regards, stephan von krawczynski UUCP : ...!cbmvax!cbmehq!cbmger!danube!thiger!skraw PHONE: +49 9938 1664 FAX : +49 9938 1598

But what about ... - DMA instead of polling, - no MaxTransfer limit (i.e. 0x7FFFFFFF), - block sizes != 512 (e.g. 20 meg Bernoullis), - driver automatically executing out of 32-bit memory, - FileSystem.resource - automatically uses 2.0 ROM filing system, - multiple controller boards supported with a single driver EPROM, - A-Max II support. Of course, I'm biased, but so is Stephan. :-) Ralph

No, I wouldn't! Get your facts straight! Ralph

All the new features - including disconnect/reconnect (see GVP's ad in the September issue of AmigaWorld for details) - were implemented in Version 3 (also called FAAASTROM) of GVP's SCSI driver. Since V3 also works with all existing GVP cards (not just the new full-DMA controllers), it is now their _only_ driver. Executing out of 32-bit RAM instead of 16-bit ROM _does_ make a difference. I don't remember the exact figures, but it was significant. Why would Dave have implemented the FASTROM and CARDROM options in SetCPU? Ralph P.S.: Since we're probably the only ones interested in this discussion, let's move it to private e-mail, ok?
