Hi,

Using 128MB SIMMs on NetBSD with a stock ROM, stock everything centris
650:

Using tmpfs:
Code:
c650# df -hl
Filesystem         Size       Used      Avail %Cap Mounted on
/dev/sd0a          3.7G       749M       2.8G  20% /
kernfs             1.0K       1.0K         0B 100% /kern
ptyfs              1.0K       1.0K         0B 100% /dev/pts
procfs             4.0K       4.0K         0B 100% /proc
tmpfs              1.3G       400M       936M  29% /mnt

Code:
load averages:  0.28,  0.96,  0.96;               up 0+00:25:12
 01:17:12
19 processes: 18 sleeping, 1 on CPU
CPU states:  0.7% user,  0.0% nice,  1.0% system,  0.0% interrupt,
98.3% idle
Memory: 419M Act, 4608K Exec, 7252K File, 12M Free
Swap: 922M Total, 922M Free

That's 400MB of tmpfs (RAMdisk in MacOS terms. :) ), and a total of
456MB physical RAM being used. It's not 520MB because I couldn't touch
the first 2 banks (interleaving means if it touches one, it touches
both) of RAM SIMMs since the kernel and supporting data exceeds the
soldered 8MB of physical RAM.
But hey. That's a respectable amount of RAM for these systems.

I personally think this is awesome! He did it by patching the booter
and the kernel.
