[9fans] Plan 9 refuses to boot from iMac

[9fans] Plan 9 refuses to boot from iMac

[Pietro Gagliardi]

Hello. Tired of waiting for Q's developers to fix the bug resulting in
QEMU, which Q provides a wrapper for, freezing every time I boot, I
decided to try to run Plan 9 on native Mac hardware. I have a December
2006 iMac with a 2GHz Intel Core 2 Duo. When I boot the iMac from the
latest Plan 9 disc, here's what I get.

	PBSI... Plan 9 from Bell Labs
	ELCR... 0C00

and everything comes to a halt. This is what I got back on Tiger when
I first joined 9fans. Does anyone know what's wrong? Thanks.

Does 9load support EFI?

OS X EFI emulates a BIOS. That's how Boot Camp works.

this stuff gets worse and worse, doesn't it.

The first OS I used a lot was MCP on a Borroughs B6700,
which I'm sure some of you have heard of ...

I thought that it's stack-based, tagged-memory hardware,
self-paging, segmented, unprotected, cactus-stack OS
which supported at least 3 character sets
and a typed file system with hundreds of file types and attributes
was convoluted and recondite.

Now I'm not so sure.

i suppose it does, if you think efi is better than bios.

You need to explicitly enable it, and even then it won't work quite
right until you get a nice bootloader that chains (much like how GRUB
does): refit is a good tool: http://refit.sourceforge.net/

I have one, but unfortunately, Broadcom hardware (remember when I
first joined 9fans)?

you can get a realtek 8139 for <$10 or 8169 nic for <$20.  you can get
a nice intel 82572 pcie card (assuming your pc has it) for $40.  a nic
shouldn't be an problem, unless you let it be.

3com Etherlink PCI cards are a few dollars each. Find a sysadmin
somewhere and he'll probably give you one if you're nice. I must
have something like 5 of these laying around in different places,
and I didn't have to pay for any of them.

"Flawlessly" would be a more accurate description.

Looks like Apple's BIOS emulator doesn't emulate a standard keyboard.
9load loops forever in i8042init waiting for "a quiescent controller".

EFI would have to support that via SMM. The bios emulator can't do it
via SMM, since EFI already owns that. It's unlikely that the apple
hardware requires ancient stuff like 8042 emulation.

So you need to get rid of pc legacy IO I bet.
