Various odd symptoms with PTI IDE drive

Last Updated: 27th November, 1994

Symptoms
Unable to install, unable to access hard drive, intermittent and odd effects after installation (HPFS, possibly FAT as well). One user reported the loss of pop-up menus (mouse RMB and Shift-F10) persisting even over a power-down and a MAKEINI rebuild of both OS/2 INI files.

Hardware
Promise Technology, Inc. DC4030VL-2 4-drive IDE adapter and PTI1S506.ADD driver.

Problem
It appears that there are problems with the PTI driver, at least with v1.2.3, v1.3, and v1.40. PTI Tech Support has said that there are problems related to the PTI driver writing to the OS/2 boot partition at shutdown, which is assumed to be FAT.

Fixes
Install to a FAT partition. Or, Use the IBM1S506.ADD driver shipped with Warp by removing the PTI1S506.ADD line from CONFIG.SYS and adding the following line in its place (assuming 2 drives): BASEDEV=IBM1S506.ADD /A:0 /U:0 /!SMS /U:1 /!SMS
