I dont find more ways to do it.
please some help
thanks

you can only do a crisis recovery with an external usb floppy because crisis recovery (for travelmate 240-250) doesn't work with usb flash storage.. I tried crisis month ago when i decide to flash one damaged bios..
I've bricked my bios one minute ago with BIOS 2.WPH.. I can't do a recovery of my bios until next week..

Hello i´m Back
After some phone calls finally i have floppy usb Smile
I make bios recovery and it works great.
I try to install bios 2 some times with same results, allways brick laptop Sad
i try to install bios1 and it works, but when i try to enter the bios i have allways black screen and i cant make any thing Sad
i dont know what can i do, but that bios seen not working bios, or bad flashing procedures, i´m flashing it from usb floppy from dos, i think that´s the way to do it well, but it dont work to me.
pd. i´m flashing acer travelmate 240 it have the same bios as tm 250, i think mod bios may work on it too on tm 240.
Any ideas please ??

More issues.
After flashing bios mod 1, i can´t enter the bios, and when i flash the original 1.15 bios the flash program said i have bios 1.13 not 1.15.
What original bios are you using to modify? the 1.13 or the 1.15
no more things to say, only that the mod bios dont work, bios.wph laptop starts normally but you cant enter the bios and bios2.wph directly brics the computer.
thanks a lot 4 your work but we need more of your work Tongue
waiting more notices.

Bios2.wph is made by PBE for simulation only ( to let you see the options before flashing ) while the bios1.wph is used for flashing and supposed to show the same options .
Bios1.wph can't enter setup as there are too many options and menus unlocked which caused overflow .
I will reduce the unlocked options sothat we getrid of this error .

The first thing to say is THANKS ahmed, for your work.
Ok i´ll be impatient to check the new bios Smile

other thing, i was reading information about the chipset of that laptop and it says it supports CPU with 1mb of cache , but i´m check a 3.2Ghz 1mb 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, cause ?????? can be the bios ??? can you upgrade it ????
that will be really great
thanks for all
