[9fans] Acer with 9atom.iso: out of physical memory

[Bela Valek]

Hi Everybody,

I try to install our favourite operating system on an Acer emachines
E525 laptop. Installation succeeded with Erik's 9atom.iso, but I
cannot boot. Here is the whole story:

- 1. Plan 9 install CD (of Aug. 15):

PBS1...
Plan 9 from Bell Labs
ELCR: 0C00
pcirouting: South Bridge 8086, 2919 not found

...aaaand hangup both in IDE and AHCI mode. not even Ctrl+Alt+Del
works. I suspect the buggy BIOS, but both Ubuntu 9.04 and WinXP worked
(the latter only in IDE mode).

- 2. Erik's 9atom.iso (of Aug. 16 22:13 PM) in IDE mode:

PBS1... Plan 9 from Bell Labs
ELCR: 0C00
sdata: blind probe 1f0
sdata: blind probe 170
aoepnp(nil)
found 54 e820 entries
Boot devices: fd0
boot from:

...aaaand nothing is accepted, CD is probably not recognized (I tried
the usual combinations).

- 3. Erik's 9atom.iso in AHCI mode works!

hard drive is sdE0, CD is sdE1, bad process or channel control
request: "dma on", touchpad is ps2 mouse, vga works with 1024x768x32,
installation successful.

-4. trying to boot, after I log in as glenda, fossil says repeatedly:

out of physical memory, no swap configured

RAM is 2 GB, partition is 2 GB, i selected fossil only, i accepted the
default in prepdisk (i admit, i didnt look at it carefully, but it was
never a problem before). Any suggestions?

Greetings: Béla

nope this is standard ich* behavior.  the
standard sd driver doesn't work around it.

i'll take a look at this.  looks like a bug.  the number of e820
entries is also curious.

what does /dev/swap say?

when its already installed, the system says at boot time: found 1 e820 entries

I checked with disk/prep in live CD mode, 9fat = 100 MB, nvram = 512
B, fossil = 1.44 GB, swap = 370.63 MB

fossil reports 'out of physical memory' immediatelly when its mounting
the partition. I cant get to take a look at /dev/swap.

Thanks for helping: Béla

can you use the boot cd to modify plan9.ini to set
*e820print=1
?

it wasn't expected that anything would change.
i was interested in the e820 output.  if you
would send that along, that would be helpful.

Oh, sorry. The install disk wrote '54 e820', the installed system
already writes '1 e820' without this line added.

however, with the *e820print=1 line added to plan9.ini,
we will see what memory range we're finding.  that's what
would be interesting.
