Symptoms

TRAP 0003 error (APAR PJ16058)
Drive does not work with OS/2 Warp

Hardware

Mitsumi 3x, 4x (e.g. FX001DE), Sony 55D, 55E IDE CD-ROM drives.

Problem

The Warp IBM1S506.ADD driver provides ATAPI support for IDE CD-ROM drives, but the above listed CD-ROM drives are not fully ATAPI compliant. The Mitsumi drives return an improper length value under some circumstances, the Sony drives fail to initialize properly.

Fix

A new driver is available from CompuServe as [ATAPI.ZIP]. Hopefully this fix will make it to TalkLink OS2BBS and ftp.cdrom.com shortly.

Notes

None.
