'ZuluSCSI is a comparatively new family of SCSI device emulators. Distinct features to older, similar devices is support for Wide-SCSI, Ultra-Speed, and a fast CPU.
ZuluSCSI also features an OpenSource firmware, so it can be extended comparatively easily.
Current state
In the scope of AS/400's, ZuluSCSI's disk support is still in its infancy, while CD- and tape emulation are seemingly solid. Some progress has been made, but there are still some rough edges, normally leading to crash of the Operating System with a given System Reference Code.
At the moment, the firmware supports only a single DASD device type.
Reports
- 2026-08-16, mikerm, 9406-170, Zulu firmware 2026-08-07. Trying to install V4R4 on the Zulu emulated DASD. Disk was created with
dd if=/dev/zero of=HD6.img bs=522 count=17177940 status=progress[1]- First try, prefetch setting at default (8k): halts at
B1934505after IPL takes place from DASD - Second try, prefetch set to 0:
B6080801after IPL takes place from DASD. More progress, and much quicker LIC install, though. - Configuration file used:
- First try, prefetch setting at default (8k): halts at
[SCSI] LogModeData = 1 System = AS400_BS522
