- Entry and the XS/Elan series are significantly different and require not only
- different software but different hardware as well. You can't "reconfigure" an
- XS24Z to be an Entry, so unless you have an old Entry graphics board around, you
- are out of luck. To go from an XS24Z to an XS24, just remove the Z-buffer board
- (labeled as ZB4.) To then downgrade to an XS, remove two of the bitplane boards
- (the small vertical ones), leaving the one closest to the back of the machine
- installed.
