I found some useful information on my trek to get two controllers working, and I thought it would be useful to some others out there judging from previous articles that incorrectly identify controller types. I know it was useful to myself : WESTERN DIGITAL: CONTROLLER CLASS TYPE INTERLEAVE WD-GEN2 XT Dual HD MFM 3:1 WD=WX1 XT Dual HD MFM 3:1 WD-3VMM1 AT Dual HD MFM 2:1 WD-3VMM2 AT Dual HD/FD MFM 2:1 WD-6VMM1 AT Dual HD MFM 1:1 WD-6VMM2 AT Dual HD/FD MFM 1:1 ST-A27X XT Dual HD RLL WD-3VSR1 AT Dual HD RLL 2:1 WD-3VSR2 AT Dual HD/FD RLL 2:1 WD-6VSR1 AT Dual HD RLL 1:1 WD-6VSR2 AT Dual HD/FD RLL 1:1 ADAPTEC CONTROLLER CLASS TYPE INTERLEAVE 2072 XT Dual HD RLL 2370 AT Dual HD RLL 1:1 2372 AT Dual HD/FD RLL 1:1 2310 AT Dual HD MFM 1:1 2312 AT Dual HD/FD MFM 1:1 2322 AT Dual HD/FD ESDI 1:1 Sorry, no SCSI or other ESDI Info. -- Adelphi University, Garden City, NY 11530 (516) 663-1170 Department of Mathematics and Computer Science markd@adelphi.UUCP or mark@promark.UUCP UUCP: ...philabs!sbcs!bnlux0!adelphi!markd

[ ton of neat stuff deleted ] If you still have all that stuff handy, could I ask for a repost telling which controllers have hardware buffering and which use the BIOS? I found that the Adaptek 2372 was a factor of three slower than the WD1006CSR2 because Xenix doesn't use the BIOS. My understanding is that some flavors of UNIX do software track buffering on any controller (which takes CPU) and some just use the controller, in which case the hardware is faster. That was a bundle of info! -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.

Add to the list the DTC728x track buffering controller. Works wonders under DOS, but Xenix cannot take advantage of it for precisely the reason you cited. That's why we switched to the VSR1 and VSR2 for Xenix use. All other applications do fine with the DTC series, I have found. -- Bote Old & Improved path!: uunet!comsea!csense!bote New & Improved path!: {zardoz|uunet!tgate|cos!}ka3ovk!media!cyclops!csense!bote
