Issues

 * The hard disk needs to be partitioned and formatted before installing this build
 * The floppy disk driver in this build is very buggy and won't work most of the time, Cabinet will either display nothing or garbage when the floppy drive is accessed
 * Even if no network is installed during setup, an error saying "Can't find NETWORK.DRV" will be displayed on startup
 * The build may hang randomly sometimes

Getting rid of startup items
Three programs are configured to run on startup by default: Dr. Watson, Chicago Beta Warning and Tracker. The former two can be disabled by removing their links (shortcuts) from the Startup folder, which is inside the Programs folder on the desktop.

Tracker can be disabled by removing it from the  value in the   section of.

Configuring a CD drive
The best way to get the CD drive working is to use an Adaptec AHA-154x SCSI adapter and a SCSI CD-ROM drive, drivers will be automatically installed and they'll work.
