Yesterday I installed FreeBSD 4.11 on my old Toshiba notebook (T2130CS,
8 MB RAM, 3 GB HDD). Since the floppy drive somehow does not work
correctly any more, I installed FreeBSD 4.11 into qemu with the right
hard drive geometry and then transferred the image using a USB hard
drive case.
Well, it almost worked. The system booted, but many things (like
compiling bsd-airtools or using dhclient, ifconfig/wicontrol, tcpdump
much) resulted in a panic with a "page not present" message.
I have set up 64 MB swap.
What I did next was replacing the GENERIC 4.11-RELEASE kernel with a
custom 4-STABLE kernel. Now everything is working fine, better than
on the Linux 2.2.26 I have on the other hard drive. Except for one
thing...
Is there somewhere a smaller X server for FreeBSD like XFree86 3.3.x?
The 4.x server eats 10 MB of RAM/swap. Well, I think I'll first try
making net/svnc work.
But, that's why I am asking here, why did the kernel panic before? Does
not not catch some out-of-memory situations correctly which went away
with the new kernel (1.7MB instead of 4.1MB)?
BTW, if anyone else has that notebook: to use 640x480x16bit on the LCD,
the pixel clock has to be reduced to 20 MHz.
