He still runs NetBSD on it). With the 750 you have to make a few kernel changes to get it to boot (these are from NetBSD, but I'd imagine that they FreeBSD changes would be similar): * in the memory detection part of the kernel (machdep.c) you need to tell it that there is 4k less base memory then there really is (it uses the top 4k for APM, but doesn't report that properly). * I used pccons and removed the initialization of the keyboard. This let they keyboard work. pcvt should support it to, although I had trouble with that and an earlier beta of pcvt. The only major problems that I had were: never got PCMCIA support working (you guys have totally different support, so this shouldn't be a problem), and the keyboard locked when quitting XFree86 (no big deal, i just made my .xinitrc reboot the machine when I left X). > do we have any support for the little red button-mouse-thing? It worked for me under NetBSD-1.0 using the NetBSD-current PS/2 mouse driver. alex
