Symptoms

Large variety of SYS errors occurring randomly during graphical portion of installation and normal use of Warp. Errors are typically of the "Application can not continue" type.

Hardware

Hard drive prefetch enabled in PhoenixBIOS Version 4.04 (possibly others)

Problem

Warp bypasses the system BIOS and uses its own drivers to control the hard drive. When the "prefetch" option is turned on in the BIOS, the hard drive returns unexpected data to Warp, whose drivers aren't aware that prefetch is enabled. This causes any data read from the hard drive to have a chance of being misread.

Procedure

Disable the prefetch option in the BIOS.

Notes

This problem seems to occur most often in Selective Install.
