[9fans] Disks not detected while installing Plan 9 on Dell OptiPlex GX1

[9fans] Disks not detected while installing Plan 9 on Dell OptiPlex GX1

[Matt Adams]

Hi folks:

I have an older Dell OptiPlex GX1 (600MHz PIII) that I am having
trouble installing Plan 9 onto.  I am using a bootable CD ISO of Plan
9 that I downloaded last night so things should be current.

The system has two 130GB hard drives installed.  Everything works
under Debian Linux.

*** Plan 9 is not able to detect the hard drives. ***

Here is what I see during the boot process:

PBS1...
Plan 9 from Bell Labs
ELCR: 0C20
islba: drive 0x80 extensions version 33.0 cx 0.5
extgetsize: drive 0x80 info flags 0x1
bios0: drive 0x80: 137,438,952,960 bytes, type 3
islba: drive 0x81 extensions version 33.0 cx 0.5
extgetsize: drive 0x81 info flags 0x1
bios0: drive 0x81: 137,438,952,960 bytes, type 3
reading drive 0x80 offset 0 into seg:off 600:0...

found partition sdD0!cdboot; 52978+1440
reading drive 0x80 offset 0 into seg:off 600:0...
biosdiskcall: int 13 op 0x42 drive 0x80 failed, ah error code 0x80
sectread: bios failed to read 512 @ sector 0 of 0x80
reading drive 0x80 offset 1 into seg:off 600:0...
biosdiskcall: int 13 op 0x42 drive 0x80 failed, ah error code 0x80
sectread: bios failed to read 512 @ sector 1 of 0x80

During the partdisk step of the install process Plan 9 only sees sdD0
as possible disks.

I have tried saying "yes" and "no" to DMA for disk drives before the
windowing system starts up and there is no difference in detected
disks.

Does anyone have any suggestions as to what I might to do overcome
this problem?  I would appreciate anything here as I am flying pretty
blind.

I am running the most recent version of the BIOS (A10) from Dell.


Thanks in advance,

Matt

would you be willing to try
	ftp://ftp.quanstro.net/other/9atom.iso.bz2
?  could you send me (offlist) the output of dmesg after having
booted debian.  i don't see any reason your drives shouldn't
be recognized, but i could be missing something.

Okay, that works.  9atom.iso found both of my hard drives.

I now see the following drives detected when I get to the partdisk
step of the install process:

sdC0 - ST3160821A
     p1	0 8	(8 cylinders, 62.75MB) type 253
     p2	8 19457	(19449 cylinders, 148.98GB) type 253

sdC1 - ST3160821A
     p1	0 8	(8 cylinders, 62.75MB) type 253
     p2	8 19457	(19449 cylinders, 148.98GB) type 253


What is the difference between 9atom and the Plan 9 ISO I downloaded
from the official website?

Will do, thanks.

that's great!

essentially, the kernel and 9load are using the sd that i've been
working on.  however the source code on the cd does matches
the official sources, not my stuff.  instructions here http://9fans.net/narchive/2009/08/359
on installing the source that goes with the modified 9load/kernel.

sorry for the messy state of things.
