- Then Entry graphics option uses an all software z-buffer. There is no
- hardware option for this graphics board. The XS and XS24 come without
- z-buffer, and do not support hardware emulation. If you want to do
- z-buffering on them you need to buy the $2k z-buffer option, which is
- real hardware.
