CPU Upgrade request Acer Travelmate 250

[srzar]

Hello i´m requesting about cpu upgrade bios on acer travelmate 250 bios

i was reading information about the chipset of that laptop and it says it supports CPU with 1mb of cache , but i check a 3.2Ghz 1mb cache 533mhz and it dont works, reading the users guide of tm250 it says only CPU 512kb cache, but i think, if chipset support it wy the computer no, i think maybe possible make some changes on the bios to upgrade support to 1Mb cache cpus ???
The Cpu web page i read was http://ark.intel.com/products/27369/Mobi...MHz-FSB%29
if you click on compatible Products it links you to another web from intel where you can read Mobile Intel® 852GME Chipset (Configurations: 3) clicking it you can read Mobile Intel® 852GME Chipset with 82801DBM I/O Controller Hub 4 Mobile (ICH4-M) that´s the chipset of tm250, but it dont works.
I search a bit more and found that webpage http://www.cpu-upgrade.com/mb-Intel_%28c...52GME.html it said the same, the chipset supports 1mb cache microprocessors
Now i´m trying to find a bios with same chipset and support for that cpu, but at the moment i dont find it, sorry
I will be grateful for all your time and all your work


You can download the original bios bios on acer´s website http://support.acer-euro.com/drivers/not...m_240.html is the same bios for tm240 and tm250

Thanks for all

Just joined the forum, I would like to thank all the great work developed here concerning to BIOS mods.
Searching through the web, for a Travemate 240-250 series BIOS mod I found this forum.
I thought the original BIOS for my Travelmate 244LC did not feature Hyperthreading technology support, but I see that the unlocked BIOS mod arranged by AHMED includes a sub menu for HTT
POC Disabled
PIC Disabled
APIC Disabled (Default)
Desktop HTT
Mobile HTT
I would like to upgrade to a Mobile Pentium 4 HTT, therefore it is neccesary to flash the mod BIOS to my laptop? or my original BIOS, actually version 1.15, would be just fine to enable HTT?.
The other requisites in order to enable HTT, chipset, processor, & OS support already met.

Thanks in advance.

My actual BIOS is v1.15:

Thanks in advance.

As there is no way to extract BIOS file from Acer Installer of v1.15, I´ve uploaded a backup of my BIOS v1.15, using WinPhlash.
File with .bak extension.
Hope it is useful.
