I think (don't have the code in front of me now) that is the only bit I probe still. Apart from that, there is an alternate probe which makes use of the printers probed by your BIOS. (I have left both probes due to the wide variety of hardware configs and broken BIOSes we all have ;-) ;-) Geoff. -- Geoff Rehmet, Computer Science Department, | ____ _ o /\ Rhodes University, South Africa |___ _-\_<, /\/\/\ email : csgr@cs.ru.ac.za | (*)/'(*) /\/\/\/\/\ : geoff@neptune.ru.ac.za |
