Aries-mu, So I finally got a 2940uw to replace the 29160n. Found another problem with paging and 32-bit disk access in win3.1. Only the first two drives handled by BIOS in the system can be used for that purpose. If going SCSI, having any IDE disks will prevent that feature from working due to …

I wish I had experience with LSI or BusLogic, but I do not. I just have a bunch of Adaptec cards. There are also Advansys cards, too, but I think those are an oem type card, but I only had one.

Adaptec does not have 32bit disk drivers for win 3.1x for ultra2 cards (cards that use ASPI8U2.SYS for the dos aspi layer/68pin port is LVD/HVD). So if you want 32bit disk access/permanent pagefile/win32, 40mb/s is your top speed with ultra1 if you attach an ultra1-wide device. Scsi2sd and such …

Coolfactor and headaches/achievements unlocked. Ultra ATA133 will saturate conventional PCI. SCSI at a similar transfer rate offers a bit more speed as the CPU doesn’t have to handle the commands, the microcontroller does it. I believe thats why SATA got a performance boost in AHCI mode, but that’s …

Aries-mu, One other thing that should be mentioned. Newer cards tend to run faster due to better microcontrollers. They have better optimizations and larger buffers. Also queuing for drives that support it. My SyQuest EZ135 is a heck of a lot faster on my 29160N than my 15xx (ISA). The drive only …

For many in the retro computer landscape, doing something just because you can is reason enough. There is very little going on here that is actually practical. Uncommon and high-end hardware combinations spark excitement, which is more than half the hobby. That is literally my motivation. …

Flexibility and compatibility. Older versions may only allow boot from SCSI ID 0 or 1, don’t have autoterminate, individual settings per ID as opposed to global settings. You need a certain bios version for zip compatibility if I remember right. I think the 2940 needed 1.25+. If your rig is simpler …

Don't confuse bus speed with hard drive speed. Even if PCI is limited to 133 MB/s, you can still have a hard disk that does 320 MB/s, since that is the speed between the hard disk and the controller (not read speed from the media!). And it's faster than a hard disk that does only 160 MB/s, since it …

Do you know what model I should look for for remote? I didn’t find anything suitable the last time I looked.

I'm guessing you haven't spent much time with SCSI. MS-DOS probably won't benefit much from a U320 controller, and could actually be slower. U320 is meant for PCIX or better, otherwise it'll tie up the whole bus. You won't get more than 133MB/s or 266MB/s (on 64bit or 66mhz PCI) out of it. Best get …

1. No idea, but you may have issues running PCI outside of 33mhz. Some peripherals/bridges are more tolerant, some are not. 2. As far as I know, 4k refresh modules are the ones to watch out for. They appear at half their rated capacity in incompatible boards. 3. I've dealt very little with EDO/FP. …

Not realllly what I was looking for, but thanks for the chuckle. I never had one as a kid and always wanted one. Unfortunately, I can't find an internal SCSI one for cheap on eRape. So far my drives are running strong. Long story short, I need to use them as it's the fastest way to move downloads …

Turning off translation had no effect. Back to no ideas.

Running Adaptec aspi drivers for the card. Iomega for the zip. It is one of the atapi versions (apparently there were three). Someone brought up a good point on winworld about scsi bios translation. I don’t know where exactly the cutoff is, but besides the Jaz, the MO drive is the only connected …

What would be a good cheap KVM for managing an old DOS machine remotely?

Having a weird issue where when a certain device is under SCSI BIOS control, the ASPIATAP.SYS driver for my Zip does something weird and DOS says it can't find any files after that driver loads and then it asks for a command interpreter location. The device is a Fujitsu 2.3gb MO drive, tried both …
