the plan 9 ide driver apparently disagrees with virtual pc.
this isn't a fossil or venti problem.

unfortunately, i have no access to virtual pc so the rest of this
email is a thought experiment ....

command 30
data f09534b0 limit f0964eb0 dlen 8192 status 0 error 0
lba 210592 -> 210592, count 16 -> 16 (16)
 0x00 0x04 0xac 0x36 0x03 0xe0 0x58
0x40: e306 0x42: c0000 x48: 00
0x4a 0000

so
	the command is write sectors (Cws; 0x30)
	lba 0x0336a0 (according to the driver)

the registers say:

0	1	2	3	4	5	6	As
	0x00	0x04	0xac	0x36	0x03	0xe0	0x58
	error	count	lba0	lba1	lba2	stat

at lba 0x3036ac (4 sectors to go) status Bsy|Df|Drdy.

i would think you're issuing a command before the device
is ready for you.  this patch may help.

minooka; diff -c /sys/src/9/pc/sdata.c  /n/dump/2008/0908/sys/src/9/pc/sdata.c
/sys/src/9/pc/sdata.c:1418,1424 - /n/dump/2008/0908/sys/src/9/pc/sdata.c:1418,1424
  	ctlr = drive->ctlr;
  	cmdport = ctlr->cmdport;
  	ctlport = ctlr->ctlport;
- 	if(ataready(cmdport, ctlport, drive->dev, Bsy|Drq, Drdy, 101*1000) < 0)
+ 	if(ataready(cmdport, ctlport, drive->dev, Bsy|Drq, 0, 101*1000) < 0)
  		return -1;

  	ilock(ctlr);

Come _on_. I'm not that subtle a "baiter," or... am I?

Which _could_ be outdated, but then if Anant Narayanan cares enough to
mirror the ISO and the sources at his own expense--on his website,
anyway--then he probably also cares enough to keep them and any relevant
information current.

Either... one created from a later compile downloadable from Bell Labs or
any of the mirrors--for example, the one at kix.in which is continually
updated. I recently had the opportunity to download it. The install/live
image I first tried on VPC anteceded this one. Unfortunately, the new one
didn't contain (or pretend to contain) a fix for this specific problem but
I'm rather sure it contained at least _some_ critical patches in the
shipped binaries; or, the whole "release-a-new-image" process is cuckoo.
Although, the last update to sources is dated April 12, 2008.

Or... the next "edition." Some 5e if such thing is ever released.

Sure not. I can't even (financially) afford a trip to the nearest
town--Greece is way out of the little volume of phase space this poor Gibbs
ensemble can sweep in any short time period from now ;-) Nonetheless,
vicarial pleasure is always an option: you go there, enjoy your trip, tell
9fans about it, I'll be reading the chronicles...

If you want to try Erik's patch, you could install plan 9 on real
hardware or under a different virtual machine like qemu or vmware, and
follow the instructions at
http://plan9.bell-labs.com/wiki/plan9/Compiling_kernels/

Or just keep using the other VM and give up on Microsoft Virtual PC
for the moment.

But, you couldn't use it even if you had it. Forget erik quanstrom's
patchworks--he may be high on IQ, but he certainly is rather low on EQ.

Wait for the next ISO release and hope for the best. Useful, stable
patches--and hopefully the one that fixes this problem--will have found
their way into binaries by then.

> Also, how to rebuild the code once i get it.

Set up another Plan 9 and compile on it?! Or cross-compile if GCC has a
"POSIX-free" target?! Use some Vita Nuova secret weapon?! Not worth it,
definitely.

Dream on. This mailing list already hosts a more-than-20-post-long thread
on how to kill rio when you are stuck. Not one soul has yet admitted
something simply needs to be fixed. All they do is CE-ly sidestepping this
non-CE-bread-and-butter guy's sane non-CE question. If you feed on
something other than thermal paste you need to find yourself a better
platform... or you could start taking up thermal paste as a side dish.

Hello Erik,
      Thank you for that.  But, I don't have the source code. Can you
please point me to the place where i can download the source of plan 9.
Also, how to rebuild the code once i get it. If there is any step by
step tutorial sort of thing, please let me know.

Thanking you,
Sasidhar.
