Hi, has anyone had any success with the patch I mentioned a while ago? (change the 512's in main.c to, say 16000) I'd like to include something in pl10 if this does fix the occasional update crashing. I'll see if I can speed up directory searching too, although it's quicker than TOS (what isn't) I still think the delay with big directories is annoying (e.g. mntlib). Steve.
