Re: Adaptec 1522A SCSI Support (was re: New TestFDC Results Registry)
I often have a 1522A in my disk imaging machine. Linux supports it, which means I can use `ddrescue` with it. It'll also talk to a lot of older/slower drives that my 2940UW doesn't like (e.g. very old DEC drives from VAXen, it does better with some old tape drives than the 2940UW). It's slow, but I've also found that it's less likely to cause a kernel panic if you're working on a disk that is very near the end of its life. I suspect that's due to being a PIO device.

It has a Centronics 50 connector, which isn't terribly useful unless you've got the right cable, but if you're building an all-in-one imaging machine, it might be handy to have SCSI capability as well. It seems the driver hasn't been in Linux for quite a few versions. Not sure about the BSDs. The 1522 was based on a lower cost chipset which Adaptec introduced to complement the 154x boards. SCSI was suffering from being undercut by other interfaces in the market due to the nonstandard bios interface that the systems equipped with the 154x boards had to run with as bios got more complicated. Also I think this was the first chip that could be in the system w/o having the bios initiate the interface. The 154x (1542 for example) required having the bus initiated and reset at boot by the bios, since there was a lot of logic involved in that chip. The 152x and the like could be fully integrated into a reasonable sized driver and only have to go the the time consuming process of resetting and enumerating devices and initiators, etc. when needed. As Richard said for use with scanners and other peripheral media. The systems became very annoying if you didn't have boot media attached to the system controller to justify all the time it took to do that on every boot. And this and the 151x controllers were priced lower. I suspect the 154x and the PCI interface controllers Adaptec had should still be in the kernel. You might be able to find the drivers and enable them in the Linux Kernel, unless some kernel driver rewrite had some feature that couldn't be implemented for this controller. I don't have a lot of references for the above, and if anyone has updates or comments, please add them. I'm still using the HP DL360 and DL380 and the like which have the higher end controllers integrated in for the only SCSI work I do, and have not followed these or other support for a long time for parallel scsi interfaces. DL360's are so cheap that buying one with SCSI drives in the Generation 5 or 6 or later is the best way I know of to run SCSI. Not great for power, but they are excellent and solid systems with a lot of OS support. thanks Jim

You can, for example, occasionally find Teac FD235S drives for sale--and if you look, it's basically a SCSI-to-floppy adapter bolted onto a regular FD235. There were also some SMS/OMTI cards that served the same purpose--floopy-to-SCSI. --Chuck
Re: Adaptec 1522A SCSI Support (was re: New TestFDC Results Registry)
For that card, no drivers are needed for the hard drives. The on-board ROM is an Int13 wedge. Regarding using any other devices like a ZIP drive, CD or a floptical, not sure if those need drivers. ZIP definitely needed a DOS driver. The CD did as well (In both config.sys and autoexec) but the ROM may have CDROM extensions already to enable booting from CD. Never tried it with that card though.

Do you have (and can you post) the MS-DOS drivers for that card? I also run one in my floppy imager machine, which dual-boots btw. MS-DOS and some later Linux. Having SCSI for at least one of the OSes would be nice. I could also switch the other partition over to FreeBSD, as Warner L suggested.

Two key components in short supply when you have 11 classiccmp projects are space and motivation, so if I can dd an old hard drive/Jaz cart/etc from the same machine where I'm reading in floppies, all the better.

Re: Adaptec 1522A SCSI Support (was re: New TestFDC Results Registry)
I use this card as a floppy/disk controller in a PC/AT that's used solely for imaging. The controller is connected to two Seagate ST-2502N (442MB) hard drives running MS-DOS 6.22. Works like a champ. Cables are readily available on eBay but since they're regular 50-pin IDC connectors, you can DIY if needed -- connectors are readily available.
