This post is being edited entirely so hopefully I won't have to keep answering repetitive PMs and questions that just keep coming up, so anymore of those, link em right to this post!
What these BIOSes do
These mBIOSes are not magical pixies injected into your P5Q series board, despite the massive praise people give them. The aim of these BIOSes is threefold;
1. Enhance memory compatibility
2. Enhance CPU support
3. Just because I can, put a half-decent boot logo in :p:
Reported additional fixes
These are things that were not intending to be fixed, but in due course of changing things got fixed.
1. Pull-ins. Apparently these pull-ins never worked, my changind of the EBB fixed them, apparently.
2. Better voltage regulation. Many report being able to OC further on less voltage as these mBIOSes have matured, this again is down to the replacement of the EBB. Typically the EBB I use is from the P5Q Premium, which uses 16 phase CPU voltage regulation. Clearly, asus undertook extensive tuning for the Premium. Using the EBB from the P5Q Premium allows users of the P5Q / Pro / -E (I think, forget if this is 16 phase or not) allows for the 8 phase designs to benefit from some of the additional tuning.
3. I think theres a few smaller things, but I forget what they are.
User experiences
This is naturally far too broad of a subject to cover fully so heres some bullet points of them main ones
* Better CPU clocking
* Better stability
* Increased FSB limits
My PC won't boot, what do I do?
Sometimes happens. The risk in using any of these mBIOSes is the same as flashing to a new official version. So heres some basic steps to take;
1. Set your system back to stock prior to flashing
If your system does not POST on restart;
2. Clear CMOS by removing battery and power cord, remember to set CMOS jumper to "clear" as well.
Tried those, my system still will not POST
Chances are the flash went wrong. Grab a floppy disk (doesn't need to be bootable) and put a known "good" BIOS on the floppy. Rename the BIOS file to AMIBOOT.ROM, hit the reset button and the system will read the floppy disk and automatically restore the BIOS with the one on the floppy disk. The system will restart a few times and before you know it you will be looking at the POST screen again.
What mBIOS do you recommend?
Its all subjective, no system behaves exactly the same. Look through the thread for anyone who uses similar hardware to you, and try the mBIOS they tried, or drop them a PM if you need more specifics. My brain may seem like a BORG collective, and to a degree thats correct, but your always better off talking to people with similar hardware to yours.
Enough talk, wheres the mBIOSes?
Here they are, I may soon upload the entire collection of P5Q series BIOS files in one package with various little snippets of BIOS files I use as well as a simple tool to inject various modules.
Heres the new BIOS pack. Within this pack are updated BIOS files for the P5Q, P5Q Pro, P5Q-E, P5Q Deluxe and P5Q Premium. The BIOS files have been updated with the memory table from the Maximus 2 Formula.
