[9fans] Plan 9 installation disc question

[Pietro Gagliardi]

Hello. I have a simple question about the installation disc: it  
didn't work on my iMac because it stuck on the second line with some  
four letter word followed by 0C00. I'm not sure what that means, but  
I think it is because it's trying to boot x86-32 when my iMac is  
x86-64. Is there a separate installation disc for each processor  
architecture? Thanks.

x86-64 is compatable with x86-32 in 32-bit mode.  one has to fiddle
cr registers &c to turn on 64-bit mode, just like one has to fiddle
cr registers &c to turn on 32-bit mode.  (maybe efi does this for you.
i don't know.)

since the plan 9 pc kernel doesn't do any 64-bit mode stuff, this should
not be the issue.

the four-letter word is ELCR.  0x0000 -> all edge-triggered 8259 irqs.

Mac OS X is still 32bit last I checked.  You're likely having an EFI related
issue.

Exactly what issue I am having is unknown to me. Does anyone know any  
place I can ask?

PS - I originally wanted to install Plan 9 on my iMac but after that  
didn't help (it froze at ELCR : 0C00 - not 0000) I wound up going to  
my basement computer, a Dell Dimension 2400 with Edubuntu (a Linux  
distro for educational purposes) and successfully installed and  
initialized Plan 9 from Bell Labs. But the Broadcom chip thing and  
having to go upstairs/downstairs is not my idea of a fun day  
experimenting :-)

PSS - The Intel chips are 64-bit ready, otherwise they wouldn't run  
OS X Leopard! :-)

Hmmm use drawterm from the Mac?

I'm having no fun trying to get Plan 9 on VMWare Fusion either :-)

That's not true either.  Early imacs, macbooks, and macbook pros weren't
Core2Duos which means they're 32bit only.

Leopard will support 32bit, 64bit Intel and PPC platforms within the last
few years.

That changes on Oct. 26 :-)

MacOS X 10.4.9+ is already 64 bit capable, at least on the
MacBook Pro

$ sysctl machdep.cpu.brand_string

$ sysctl hw.optional.x86_64

$ cat > ilp.c <EOF
#include <stdio.h>
int main(int c, char**v) {
    printf("i:%d l:%d ll:%d p:%d\n",
	   sizeof(int), sizeof(long), sizeof(long long), sizeof(void*));
}
EOF

$ cc -m32 ilp.c -o ilp4
$ cc -m64 ilp.c -o ilp8

it's increasingly offtopic but yes :-)

The whole system is not 64bit end to end.  Objective C and Cocoa aren't yet
64bit, and I've yet to fail to get alignment errors with certain C memory
allocation functions on my MBP with Tiger.

I hope it's all fixed Friday, not that I see me using 64bit apps too much, I
don't think I have enough RAM, even if the extra registers give me a bit of
a performance boost  :-)

OK, that's fine. So I still don't know what is wrong, but I'll try  
drawterm when I get Plan 9 up on the network (see my Broadcom emails;  
I'm buying a card soon)

I gave up on graphics for VMWare Fusion Plan 9, going to resort to drawterm
I think.  However my venti is hanging and the CPU on my MBP is getting
awfully fast on the first boot after install and I login with glenda.

I was trying this out via Boot Camp, and it stuck before the CD menu  
even showed up. At least you got it booting! :-)

i thought a few others on the list might be interested in this one (unless you're Jeff Sengstack,
who hated it)

amazon's key phrases are a little odd:

 Key Phrases: core memory, Gene Amdahl, Defense Department, World War

i see that it offers a unique description of the first production Google machine, too
