The BIOS is not ACPI compliant

[agentdax5]

I was trying for a long time to get the SLI mod for any motherboard for a while but I've given up. I want to return the second video card I was using back to my friend, but whenever I remove the second card I get a bluescreen on boot up.

The BIOS is not ACPI compliant
STOP: 0X000000A5 (0x00000011,0x00000007,0xf20c0180, 0x0100000B)

Now this can't be real considering it boots fine with the second video card installed. I've tried using 3 different versions of my motherboard's BIOS that ASUS has on their site and all have the same result. What could be going on?

make sure ACPI is enabled in bios after the card is removed

 

[agentdax5]

It's always been enabled

Is this during post (when you turn the PC on) or when it tries to load the OS?

 

[agentdax5]

It tries to load the OS.

Is it possible you made contact with the dimms (your ram) when removing the video card? I suggest your ram and examine them.
-were they well seated in the socket(s)
-are they any hard scratches on the gold fingers of the dims
-etc

Also, check and make sure that 24-pin power connector is seated correctly. Check other connections as well. Oh btw, make sure that the video card is in the correct PCIe slot.

Of course they were seated correctly. RAM is fine. I'm using the afflicted PC now with the second video card installed...

he used the SLI mod here on TPU, and its screwed up.

Unless you can find a way to un-do the mod, you're gunna have to repair/reinstall windows.

repair doesn't repair it, tried a lot.

Probably some stupid oem windoze routine that checks configuration and saw it's changed and then nagging you. Go for enterprise or ultimate version.

Here's what m$ disclose on that code issue

(0x000000011, Parameter2, Parameter3, Parameter4):

The system cannot enter ACPI mode. There are many reasons for this, including:

* The system cannot initialize the AML interpreter.
* The system cannot find the Root System Description table.
* The system cannot allocate a critical driver.
* The system cannot load the Root System Description table.
* The system cannot load device descriptor blocks.
* The system cannot connect an interrupt vector.
* The SCI_EN (system control interrupt enable request) cannot be set (see 0x00000001).
* The ACPI Table checksum is incorrect.

ACPI is a hierarchical arrangement of tables, each one building upon the next to define the complete capabilities of the system and of every device in the system. ACPI starts by looking for the Root System Description table, which points to the next table, which points to the next table, and so on. Usually, the 0x000000011 error occurs because these tables are damaged or missing.

OEM installs usually needs some low level tool to zero the whole disk out and then to go with clean installation. Is this Vista or Win7

make sure ACPI is enabled in bios after the card is removed

ACPI is not same thing as PnP (PlugnPlay).
