[9fans] iso won't boot on T61

[9fans] iso won't boot on T61

[lejatorn]

Hi all,

I've just got a brand new T61 on which I'd like to install plan9, but to
no avail so far.
First, and I'm not sure whether this is normal or not, the boot cd does
not find what to boot from and requires that I enter the kernel path, 
which seems to be "sdC0!cdboot!9pccd.gz". That one starts booting 
fine, but it soon hangs after those lines are displayed:

cpu0: 1995MHz GenuineIntel Xeon5000-series (cpuid: AX 0x06FD DX
0xBFEBFBFF)
ELCR: 0C00
pcirouting: Cannot find south bridge PCI.255.31.7
mapfree: unallocated unbacked physical memory: losing 0xFED20000,
19791872
#Y0: Ricoh 476 PCI/Cardbus bridge, F8300000 intl 10

Can anyone help with that please?

Cheers,
Mathieu.

[9fans] portuguese - european keymap support

[Paulo]

Hello,

I'd apreciate if someone is willing to help add support for the
Portuguese - European keymap.

What must be done?

Thanks.

There is a keymap for ABNT2 keyboards in x_spager contrib dir.

In principle it's actually quite simple. First have a look at kbmap(1) and
kbmap(3), then put a new mapping together. You might want to start with one
already in /sys/lib/kbmap/ and work from there. (I don't know exactly, but
the spanish map might make for a good starting point.) Altogether not too
complicated, but still some gruntwork. And when you're done, don't forget
the patch.

Thanks. I'll be looking into it.

Ok, turns out all the problems were coming from my hdd in SATA mode,
seems like it's not supported by plan9 yet...

The iso boots fine if I switch the drive to ide compat mode in the 
bios. Of course, that means if I want sata when booting on linux (which
is also installed on that machine) I need to switch it back again 
everytime. :/

Any chance of SATA for that drive to be supported in the near future on
plan9?

Also I'd like your opinions on sata vs pata please? Like, is operating
the hdd in compat mode in Linux a big loss compared as if operated in
AHCI mode? Do I loose speed for example?

Cheers,
Mathieu

Re: [9fans] Re: iso won't boot on T61 [reason found]

[erik quanstrom]

could you send me the output of pci from
your plan 9 machine?  it would also be helpful
if you could copy down the output of the e820 scan
and send that along.  sata (ahci) should be supported
on your machine, i believe.

on a laptop, i don't think one would notice a difference in 
transfer rate.  the main advantages of sata are support for more
than 4 devices and support for more than 2 devices on non-shared
links and support for hot plugging.  it is also easier to mix
pata & sata drives if the sata drives are treated as sata drives.

Here's the pci -v log.
How do I get you that e820 scan?

Thx for the tip. Then if I can't get sata to work on plan9, maybe I'll
modify my linux install so that it uses pata (so that I don't have to
switch it in the bios everytime I switch of os).
