Hello,

Can anybody tell what's the exact purpose of the 2 flags present in the BIOS dump (32 MB) of an HP 840 G5, on the BIOS region, EfiSystemNvDataFvGuid, VSS2 Store:



There seem to be 2 flags, both set (0x01, 0x01) and I wonder if those have something to do with the MSR Lock (CFG Lock) related to power management used by Macintosh systems...

Thanks in advance....

Re: HP G5 840 BIOS CFG lock?

Just as a followup, could it be that this configuration has different naming in HP? The goal is still the same, allow the SO to write a specific register (normally protected) related to power management.

Hello,

I'm trying to get an HP G5 840 BIOS to allow writing to the MSR 0xE2 register ([B]CFG lock[/B] bit unset). The purpose is to allow a hackintosh installation write to the power management settings needed by MacOS, for stability reasons since the available hacks seem unstable with frequent freezes/crashes of the system.

With other manufacturers this seems quite easy, but with HP I'm quite out of luck. Is there anybody that has successfully patched an HP Elitebook BIOS to allow for this CFG Lock modification?

In there's any chance this can be done,...
