Help... Kernel Panic after editing DSDT

[melon]

I was trying to edit my DSDT... Experementing....
After restart, I can't boot anymore...
I also tried -x (safeboot) but still gets kernel panic.
Ow men... How can I boot now...
I've some files placed there and haven't backup yet...
How can I boot up again?

Here's what i found out at -v (verbose mode)

Panic(cpu 0 caller 0x5591db): Unable to find driver for this platform: \"ACPI\".\n"@/SourceCache/xnu/xnu-1504.7.4/iokit/Kernel/IOPlatformExpert .cpp:1389

Boot from the iBoot disk.

This will bypass the new DSDT and allow you to boot to desktop to fix the issue.

You know MacMan has a DSDT ready for your board right?

What is the edit you are trying to make?

Try booting with iBoot and SL DVD...
And try restoring a working DSDT via the Terminal, or move /Extra aside and reboot.
You can then restore a good DSDT into the saved /Extra, restore it to /Extra, and reboot.

Another option which might work is boot with iboot, specifying DSDT=/dev/null

When hacking DSDTs, I always keep a working copy under /Extra/DSDT.aml, and use 'DSDT=/Extra/DSDT2.aml' in chameleon to read the hacked/experimental one.

Good Luck !

That's a great tip!

Resurrecting this thread for a sec. My GA-P55-USB3 has finally given up after its CMOS was wiped by the RTC wake from sleep issue. The CMOS chips or controller were damaged a while back when some idiot(ME) shorted the CMOS jumper while the power was on. After that it would only run properly if I used F7. Any later Bios would cause it to have a long beep and not boot. Now I can't get it to boot at all. I'm replacing it with a GA-H55M-USSB3. Since the GA-P55-USB3 DSDT is installed in my /Extra I'm expecting it to crash. I was wondering if someone can tell me how to delete or move my DSDT from my Lion install using iboot & terminal to head off the problem?

Thanks,

It occurred to me that all I needed to do was get an enclosure for one of my lion installed drives and connect it to my Macbook Pro by USB. I was able to remove the DSDT.aml from /Extra and remove the cache file also. Hopefully it'll work when I put it in my GA-H55M-USB3 tomorrow. I am wondering about ownership and permissions but hopefully it won't be a problem....

Any solution to this? I've got the same board and my DSDT causes a kernel panic at boot... booting with -s and "rm -rf"ing the file removed it so I could boot up. Without the DSDT I've got no graphics or mouse support so it would be nice for it to work!
