Quick question: is anyone aware of a 32-bit SCSI (or SCSI-2) controller card for PC-compatibles (i.e., an EISA version of a SCSI card)? We are purchasing a 486 EISA machine, and we would like to take advantage of the 32-bit bus. Alternatively, does anyone have recommendations for SCSI controllers that would have a high throughput (even if not 32-bit)? Thanks. Tom Solomon solomon@chaos.utexas.edu

And DPT should have a caching/mirroring/etc. model (PM2012B) available in a week or two. I just purchased two DPT's PM2012A/95 (non-caching 32-bit EISA SCSI(-2)) cards from Direct Drives, $599 a piece. Jukka

A very fast SCSI card for teh EISA bus is the ADAPTEC AHA-1740. It offers a 1540 ("compatibility") mode for old drivers, as well as the fast enhanced mode. Bob piety@hplred.hpl.hp.com (415)857-4759

What is 'very fast'? In what environment? Mylex is best EISA-SCSI controller, what I have tested, but it doesn't fit to the OS/2-wordl, because of missing HPFS (working ones) drivers. Adaptec 1740 works allright with OS/2 HPFS, and with SCO Unix, but the performance is not so good, as with Mylex. I think it is mostly because of missing HW-cache on-board. -- --------------------------------------------------------------- Matti Joutkoski, mattij@yj.data.nokia.fi, tel. + 358-0-5673866. ---------------------------------------------------------------
