Hi,
I used Erik's 9atoms.iso to install Plan 9. When its booting, after
its asking for root partition and username, I get the error message
repeated: "out of physical memory; no swap configured". Why, oh why?
I use fossil without venti, on a 2GB partition, the RAM is also 2 GB.
I found the message in
http://plan9.bell-labs.com/sources/plan9/sys/src/9/port/swap.c -
static void pager(void *junk).
Greetings: Béla

memory scan went sideways due to broken bios? the memory
messages printed during startup should be helpful.

I attached a screenshot (sic!). You can see that Plan 9 found only 8
Megs of RAM, also there is the reflection of my cousin and me, sorry
for the fingerprints :)
How do other operating systems detect the available RAM? Could Plan 9
use the same method?
Also, I didnt install Venti.

plan 9 uses the same methods for detecting ram
everyone else does. perhaps we trust bios too much,
but 8mb isn't impossible, either.
try
a *noe820scan=1
at the 9load menu prompt.

Hi,
I tried it and didnt work, I got the same output. Maybe its time to
trust BIOS less... :(

I had this error on VMWare recently. The solution was to disable Venti and
just use fossil. Venti is of questionable value when I'm already
snapshotting my host's filesystem anyway.
I think the real correct answer is to set Venti up with the correct
parameters by hand before restarting. I didn't try that though.

Hello!
When you are done setting up the system do not reboot right away,
rather reconfigure venti (via venti/conf) with small enough memory
settings. Then you can restart safely.
