On a 64 bit Linux system, by default only 64 bit libraries are installed (duh), but usually you can install 32 bit libraries to support 32 bit binaries. Exactly how to go about it of course depends on your distribution.

Re: SCSI2SD: Is it worth a try?
The system I use (OSX) to mange the SCSI2SD cards configuration and firmware doesn't have a SCSI. I'd think of it more as a "nice to have" than a requirement. The V6 cards allow data exchange via USB2. If you have the appropriate images, you can just DD the data directly to the microSD cards on OSX and Linux. I move and backup images for RT11, XXDP, NeXT (Intel and 68K), SunSparc, Linux and VMS this way. The V5 cards have shown themselves to be quite versatile in my shop.

Re: SCSI2SD: Is it worth a try?
I too have been using these for a few years; also on mostly 90s workstations and servers (Sun, SGI, Alpha, Apple, etc). I think I have about a dozen or so V5 boards. I've not tried the V6, as I've heard numerous stories of poor compability. The multi-mode emulation works fine. I booted my Sun SPARCStation 10 from a Solaris ISO using CD-ROM emulation mode and installed the OS onto an emulated HDD running on the same SCSI2SD. --- Jim Stefanik Dallas Vintage Computing Center From: Sophie Haskins via cctalk Sent: Tuesday, 19 March 2019 07:58 To: Charles Dickman; General Discussion: On-Topic and Off-Topic Posts Subject: RE: SCSI2SD: Is it worth a try?

Re: SCSI2SD: Is it worth a try?
Is it perfect? No. Is it worth a try? Absolutely! I have both V5 and V6 and they work very well "most of the time". Some machines just don't like them (usually in the form of frequent bus resets). Some machines work better with the V5 and others better with the V6, and sometimes settings need to be tweaked, but overall I am very happy with them. I use them mostly as a CD-ROM replacement for installing the OS, and it saves enormous amounts of time and CD-Rs. Speed is definitely not an issue.

I a pre-V6 one for my Atari but have never used it in the Atari. It is now in my IBM PC Server but its only used for backup. Its in a single ended SCSI-1 card and its noticeably slower than the fast/wide spinning disks in the RAID array. > > Versions up to 5 seem to be GPLed and reasonably available.

Neither a V5.1 nor a V6.03 worked with my MicroVAX 3100 M95, it's built in SCSI interface and OpenVMS V7.3. Light access worked but as soon as you tried any kind of actual work it threw hoards of mount verification messages and errors piled up and became unusuable. On the other hand, the V5.1 worked terrific on my Compaq AlphaServer DS10 with a Qlogic ISP1020 SCSI card and OpenVMS V8.4 Others have had success with MicroVAXen and V7.3 and earlier so I think it's my system, but I haven't had time to work it out yet. -- John H.

I am curious about how well it works and which version to get. Depends on the machine and the OS. Worked well in a PowerBook with MacOS, but NetBSD on my IIci threw all kinds of problems with it. Works great in my Solbourne S3000, but opened the SCSI fuse on my rare PowerBook "800." I don't know if v6 is appreciably better. Most of my experience is with v5.
