Adaptec (Trantor) 358 Parallel-to-SCSI EPP MiniSCSI. May require "settings", e.g. "/m2 /i7". Works outta-da-box with W95, required several re-installs under W98 but works fine (versus driver supplied on W98 install CD didn't work at all). Boot with SCSI peripheral device awake & functioning (e.g. if CD-ROM drive, should have valid CD inserted in tray).
