Done that. I have set everything as small as possible but this didn't help. After a BIOS upgrade, I found the promising option MAX TOLUD which was set to 2GB. I changed it to 3GB but nothing changed. > > Also, I'd like to know reasons that made you stick to 32 bit OS > as we have pretty good support for 32 bit applications running under 64 bit > system. I (still) have 32 bit machines and don't want to maintain 2 userlands. Each machine has its own kernel but userland (updated via nfs) must remain 32 bit. Or is it possible to boot a 64 bit kernel and have everything else in 32 bit? _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
