Hello all,
some time ago I got XL-525 controller and tried to use it to connecting SCSI devices I have but with partial success. I think it might be some termination or incompatibility issues. But I can't find any docs and software for it except of (incomplete) jumper settings and experimental Win95 and WinNT drivers. Perhaps someone has or someone knows where to find the full documentation, configuration utility and DOS drivers?

Welcome to Vogons 😀

Is this where you're seeing the jumper info ? https://stason.org/TULARC/pc/hard-disk-floppy … -seven-SCS.html

As for drivers, as the card is based on a QLogic FAS216 chip, you could try the drivers here (either the DOS or Distribution Disk links might be the best places to start) https://web.archive.org/web/20001017121237/ht … /vl_fl_408.html

Yes. Inattentively I missed the description of JP15. But now I found it.

Thank you for this link. I've already tried QLogic Fast SCSI! drivers for WinNT, but unsuccessfully. Perhaps the drivers and software for DOS will work if everything is configured correctly.
