Hi there, I got MacMinix from PH about 2 days ago (and haven't really slept since then :-) and have been working on setting up my system. I have been reading this newsgroup for about two months, and have pretty much picked up all of the MacMinix & Minix tips that I needed to get my system going (Thanks!). To make a long story short, here's what's happening: When I rebuild the kernel, mm, fs, and tools, I get mixed results depending on how I set NR_BUFS and NR_BUF_HASH in /usr/include/minix/config.h. Results are as follows NR_BUFS NR_BUF_HASH Bomb ------- ----------- ---- 30 32 No 60 64 No 120 128 Yes 160 256 Yes ... anything higher also bombs When I set these parameters to any of the "Bomb:Yes" values, MacMinix says "Can't find fs" during the boot cycle, after loading in the kernel and mm boot resources. Resedit shows that the fs BOOT resource is indeed in the macboot file. Does this perhaps have something to do with a Mac resource size limitation? For the 60,64 setup, sizes of kernel,fs are 135668 and 101345 bytes respectively. When set to 120,128 the sizes become 136388 and 165321. I'd test more values, but I'm sick of rebuilding Minix. Has anyone tried building the system with ThinkC ? What's involved in doing that? On an (un)related note: My mean time between failures varies depending on what I do. If I move the mouse outside the TTY0 window, I'm sure to hang the system within a minute or two. Otherwise, MINIX will last for about 20 minutes, more or less. uncompress'ing 50k or more files will usually cause an illegal instruction error. Is this situation comparable to what other MacMinix'ers are seeing? For reference, I'm running MaxMinix 1.5.10.1 from PH with the double GentNextEvent problem patched in console.c. Everything else is stock. My system is a Mac II with PMMU installed, 8MB ram, running System 7.0b4. The &.0b4 part worries me a bit, given MacMinix's poor showing with MultiFinder. Is anyone else running under 7.0? Thanks in advance, -- David -- David Creemer | MCC Software Technology Program | creemer@mcc.com 512 338-3403 | 3500 W Balcones Center Dr., Austin, Texas 78759-6509
