BIOS listed below are the latest HP bios with 1 (Santa Rosa) / 10 (Montevina) bytes altered to allow a dual-IDA overclock. These will flash OK however standard disclaimer applies: you will be responsible for any damage to your computer system or loss of data that results from using a system with a modified BIOS. Ensure your system's cooling system is working well before trying any overclocking. These BIOS are not tested or approved by HP.
Introduction
I noticed that mostly Dell and Alienware Core 2 Duo systems were dual-IDA capable from the factory. I proceeded to successfully modify and test the 2510P dual-IDA bios, extending the modification to other Santa Rosa HP Business notebooks, plus the ULV/LV 2530P and 2730P. Find the resultant modified bios-es below:
| Flashing a dual-IDA bios will provide an extra multipler, gaining 5-17% more CPU performance on an IDA-capable CPU when using Throttlestop. Examples shown on the right. Throttlestop also provides IDA overvolting and superLFM undervolting to provide greater setfsb overclockability on AC and increased battery life on DC. Combining dual-IDA and PLL overclocking will give the greatest possible overclocking. Installation Instructions Windows users Download package of interest in the Version column on the right, double-click, extract to a desktop folder then run the HPQFlash file and follow instructions. The supplied HPQFlash is modified by TTAV134@mydigitallife to allow successful flashing of a modified bios. If HPQFlash doesn't do anything and you see a LOG file containing an entry WMI BIOS Flash function is not supported on this system, then install HP Quick Launch Buttons on your system and try again OR perform a DOS based install like for Linux users below. Linux users (Santa Rosa) Download and install modified rompaq from here. Download bios file of interest from above, extract rom.bin from the ROM.cab and copy it as 68***.bin on your DOS bootable USB thumbdrive. Reboot using the USB drive and install bios using the rompaq utility. |

How to setup Throttlestop to use the extra multiplier the dual-IDA bios provides?
See 2.0's great guide here skipping step 1 and step 2.
Flash gone wrong?
(Santa Rosa) Use Emergency Recovery. You must use a USB floppy drive. A USB thumbdrive doesn't work.
(Montevina) Use HP EFI BIOS Recovery.
Conclusion
dual-IDA/setfsb overclocking system wrings every last bit of performance out the system. Perhaps enough to tide things over until Q1 2011 when the worth-upgrading-for Sandy Bridge mobile platform is released?
Please report your results so I can update the Tested table field above.
