Laptop CPU Problem
Posted: Tue Jan 22, 2008 7:03 pm
Using a Toshiba M73 whihc came originally with a Celeron-M 390. UPgraded to a Pentium-M 740 and I have a problem with it.
It is detected by the bios and windows as a Intel Pentium-M 740 at 1.73Ghz, problem is it is only running at 798 Mhz with a multiplier of x6 and a voltage of 0.988.. Now, here is the problem.. The Bios has the latest rev of the microcode for this processor (06d8 rev 20), but the settings are way off.. As this bios is customized by Toshiba themselves, the SpedStep/Power options have been removed from the bios as this machine didn't include a processor that had this option, even tho the chipset (ATI SB450/Mobility Xpress 200M) does have Enhanced Speedstep included, but disabled by bios.. Can I modify the ACPI table manually and then reflash to run correctly? As well, how would I go about doing this? Its hard to find tools for a Phoenix bios that will support the TrustedCore system. Bios Editor 2.2.0.1 will allow my to look at the ACPI table, but, I am not positive how to change the info as it doesn't seem to be specific to one processor but how to get the info from the chip.. Thanks.
