I bought the thing just for plan9 too. it's got the right soundcard the right pcmcia controller jmc has been helping me he's already had to make me a custom .9gz file for the install cos the laptop thinks it's having sanity problems which may or may not be true quoting jim "it's broken in the sense that it persistently reports there is a hardware error. from the earlier trace MCA 0011c160 MCT 00000009 means there was probably a parity error on either a bus or memory transaction " I do have a question though, wasn't VESA compliance supposed to do away with these problems I downloaded the QNX demo disk and that gave me a choice of 5 or 6 screen modes which all worked. I don't pretend to know anything about VESA compliance other than I remember it bringing true colour cards to the early windows world and helped some game writers get around the drivers problem. Matt
