[ubuntuforums] Foxconn deliberately sabotaging their BIOS to destroy Linux ACPI - Overclock.net

I disassembled my BIOS to have a look around, and while I won't post the results here,I'll tell you what I did find.

They have several different tables, a group for Windws XP and Vista, a group for 2000, a group for NT, Me, 95, 98, etc. that just errors out, and one for LINUX.

The one for Linux points to a badly written table that does not correspond to the board's ACPI implementation, causing weird kernel errors, strange system freezing, no suspend or hibernate, and other problems, using my modifications below, I've gotten it down to just crashing on the next reboot after having suspended, the horrible thing about disassembling any program is that you have no commenting, so it's hard to tell which does what, but I'll be damned if I'm going to buy a copy of Vista just to get the crashing caused by Foxconn's BIOS to stop, I am not going to be terrorized.

Fix Foxconn sabotage:

Find, the section that starts out with

Code:

Code:

            If (_OSI ("Windows 2000"))
            {
                Store (0x04, OSVR)
            }

Go down til you get to the first

Code:

Code:

        }
        Else
        {

Past that you should see Linux alongside Windows NT, which is above another Else that leads to Windows Me.

Should look like:

Code:

If (MCTH (_OS, "Linux"))

{
Store (0x3, OSVR)
}

Change it to:
Code:

Code:

            If (_OSI ("Linux"))
            {
                Store (Zero, OSVR)
            }

An IF statement was the only thing preventing it!? Hardware is in a poor poor condition if it depends an OS. Next we'll have Vista only PSUs.

Program much? Its always the the if statements...

I believe it was only a poorly written bios, and not a malicious device to dissuade users from using another OS.

Shh, the tin foil hatters need another thing to hate corporations for. Don't let common sense and logic get in the way of that, that's just evil!

Wait a minute..... This guy rewrote his bios and patched the whole thing himself, and you're telling me that Foxconn didn't have the time or manpower?

I'm calling shenanigans.

No I don't believe that there is enough evidence to suggest Foxconn deliberately sabotaging Linux, because he would have found that we he tore apart their half-asses attempt at a bios. I do believe that there is enough to exclude Foxconn from my purchasing list for not caring enough about their customers to provide a true multi platform capable product.

There is probably a bios update that fixes this.

Truambitionz · 07-25-08

Conspiracy.

Licht · 07-25-08

Doesn't look sabotaged at all, very misleading title.

trueg50 · 07-25-08

Very misleading and paranoid.

I don't even thing Foxconn writes the BIO's, it is some other company.

Coma · 07-25-08

Why misleading? There is an ACPI table made *just* for Linux that causes weird problems, while the Windows ones work just fine.

Why go out of your way if using a single table works just fine? There's only one answer...
