I had problem after problem with many Mylex/BusLogic boards till I started using active terminators on the end of the chain. Some of these controllers are also quite picky about sharing an IRQ with another PCI card. You might have to play with the BIOS settings of the motherboard to allow the card exclusive use of an IRQ. Of course, if that does not cure the problem, change the settings back :) Double check the cables, use active or forced perfect termination, and check the IRQ the board wants to use. Has Mylex discontinued this board? A couple years ago they discontinued nearly all of their SCSI products. -Toth

Mylex's website states that they are an IBM business unit. www.mylex.com Richard Erlacher wrote:

But you probably know all that.... Doc

Have you set Plug & Play OS? to NO in the computer's BIOS setup??? Have you gone into the PCI / PNP set up in the bios and manually assigned IRQ's? At 10:16 PM 2/3/02 -0700, you wrote:

I simply plugged the board into a motherboard that had no other plug-n-play resources in use (on-board stuff was pre-assigned via "heritage" assignments, and that got the controller to see its drives and format and subsequently configure them. Unfortunately, having now done that, it doesn't boot Win95, though it is booting from the IDE drive. That's going to be a problem. Another problem is that the Win95 version uses FAT16, so it doesn't recognize the striped pair as a large drive, since it can't deal with drives >2GB. I'm not sure what to do about that, however.

BusLogic/Mylex also made very nice programming manuals which were freely available when Adaptec still wanted an NDA and other paperwork signed to get sketchy documentation for their products. Once Adaptec changed their programming documentation policy, Mylex seemed to take a large drop in sales. -Toth

I found a boxed MCA scsi controller from BusLogic (BT646?) a couple years ago, but don't have a PS/2 I want to put it in yet. I'm waiting till I find a decent MCA based 486 before I use it. I've got a few other assorted BusLogic/Mylex non-raid boards laying around somewhere. I wouldn't mind finding some VLB or different EISA cards tho, since they would be good for testing driver software. And speaking of MCA, what kind of slots are available in a P70? I've got a couple 3c527 boards I was thinking about using, but they are 32 bit. -Toth

nowadays. Not your call to judge the owner's intent. You have to ask. Right? John A.

I know that he won't boot from SCSI unless he disables the IDE controller but otherwise the Mylex should work in his system. Make sure that IDE is disabled and that the drive types in BIOS are set to none or 1 and see where that gets him with it. => -----Original Message----- => From: owner-classiccmp(a)classiccmp.org => [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Richard Erlacher => Sent: Sunday, February 03, 2002 9:56 AM => To: classiccmp(a)classiccmp.org => Subject: OT: Mylex problems => => => A friend has come to me with a problem I don't seem to be able => to solve.

I don't think he wants to boot from the SCSI, but he does want to exploit the striping capability of the MYLEX board. What's more, he's going to want to attach both narrow and wide drives, though I doubt the MYLEX software will allow striping across different drive sizes. Right now, I simply wish I could force the assignment of specific resources to the MYLEX board via the Plug-n-Pray logic, but that doesn't seem to work.

I recently bought a brand new small (9.1GB) FUJITSU SCA-2 drive for $31+ shipping. 2-giggers go for about $7+freight when you find 'em around here. The -N drives wouldn't help, since the controller is WIDE SCSI.

If you find a backup application that works reliably (allows you to restore from its backups, performs scheduled unattended backups and unattended restores.) under Windows, please let me know.

Right now he just wants a striped pair. The problem is that the controller is in conflict with other system plug-n-play resources, hence external features, notably interrupts, don't work. I've set up a couple of other MYLEX boards from the same series, albeit not just single-port versions like this, and not under Windows. I've used Unix, LINUX, and Unixware with 'em and they were pretty satisfactory. What I need, if there is such a thing, is the ability to "FORCE" a set of resource assignments onto the board. It seems to be at odds with the system's resource assignments.
