The DSDTs are sorted by board type and date. Check to see which version of the P55A-UD3 board you have, v1 or v2. The F# refers to the bios number, 11 being the latest. You'll have to check to see what bios your board is running.
Since you're able to boot to a gray screen and cursor, my very...
Same here. Leaving my USB external backup plugged in would give me EBIOS errors two out of three startups. Unplugging the external except when needed removed the EBIOS errors.

Quick edit: to check, go to System Profiler and click on Software on the left hand side. It'll have 64-bit Kernel and Extensions: Yes
Hmmm, with the same board I have AppleHDA.kext in /S/L/E and Legacy888HDA.kext in /E/E. That doesn't look right, but if I remove either one of them I lose audio. Go figure.
I couldn't tell from your post if you have any external drives connected. I had the EBIOS read errors until I unplugged my external hd before startup. I now leave it unplugged until time for the weekly backup. HTH
I was thinking copying your Extras Æ’ and your Extensions Æ’ to the desktop, then dragging each of mine to replace your whole Æ’ in both instances. Afterwards dropping each folder onto kext utility should give you a new .mkext for E/E and a new .mkext for S/L/E. But you say you manually put...

All you need to boot 64-bit is to remove the "arch=i386" string from /Extra/com.apple.Boot.plist
32-bit
<key>Kernel Flags</key>

64-bit

If you open System Profiler and click on "Software," it'll tell whether or not you're...
