I believe it is turned on by default.

It did NOT help.
Anyway, system is toshiba satellite 4030CDT with 64Meg of ram. Strange thing is that I'm not able to boot with mem=63M. mem=60M works fine, mem=8M works, too.
During bootup (and before crash), I can see a list for a short while. Therefore, I copied only (usable) + interesting lines.
654336 @ 0 (usable) 65929216 @ 100000 (usable) 512 @ 100b6e000 type 4
It looks sane to me.
Does it help? Pavel -- I'm really pavel@ucw.cz. Look at http://195.113.31.123/~pavel. Pavel Hi! I'm a .signature virus! Copy me into your ~/.signature, please!
