Can't get to 32-bit mode

wziard · #1 09-29-2009, 02:19 AM

I have been trying for hours to solve this problem and can't figure it out.

I have a nearly flawless Snow Leopard installation on my Asus P6T Deluxe V2 system, but it only works in 64-bit mode. This is fine for pretty much everything except one major issue, which is wireless cards... none of them work with 64-bit.

When I try to boot with the -x32 flag (using Chameleon), it goes to the normal boot screen and panics after awhile. With -v it always hangs at ACPI_SMC_PlatformPlugin, however I don't think this is the problem because lots of people have this item failing while booting, but it doesn't give them problems.

I CAN successfully boot with -x32 -x (safe boot), however it always kernel panics within 5-10 minutes and numerous other things don't work (wireless does, though).

a
So the problem is that I can boot to 32-bit mode only using the -x flag, and it hangs without it. I have no idea why. Any ideas?

Yeah, I installed Chameleon 2 RC3 and tried booting with arch=i386 -legacy. The result was fcsk failing, some messages about kext loading disabled, cpu halted, and then the system shuts down.

try arch=x86_32

Information:
arch=i386 -legacy : Boots into 32 Bit Kernel Mode AND!!! 32 Bit App only
arch=i386 : Boots into 32 Bit Kernel Mode , 64 BIT Apps can run also

So normally use NOT the -legacy !

If I recall arch=i386 wont' work with Chameleon 2 RC3

For me arch=i386 is working CH RC 3 and also know as usual 32 Bit flag since RC 2.
The other flag is arch=i386_X64.
For my knowledge flag arch=i386_32 is not used by any bootloader.

I tried arch=i386 and arch=i386_x64 boot flags, and both seem to load everything but hang towards the end of boot after loading ethernet texts. Usually the last item is ACPI_SMC_PlatformPlugin having a timeout error, but I still don't think this is the problem.

What GPU ? It can be that GUI is shown but you cant see it !!
What happens if you type in kernel flags arch=i386 -v -x ?
So you have an multi system (Leo + Snow Leo) on one HD (2+ partitions) ?
If yes, perhaps wrong /Extra conten is used - which partition is active ?(means must you press F8 to select the Snow Leo or not) .

-x boots, but I always get kernel panics within a few minutes and random things (like Spotlight) don't work.

GPU is nVidia GTS 250, and I think it's working properly since I can see all the necessary things for it being successfully loaded with -v.

My SL installation has a drive all to itself, the Leopard install I referenced was on a different drive entirely.
