Hi, note: ( I put in DOT in some link to enable post) I am trying to flash a Modified BIO for my Fujitsu T4220 with the following file downloaded from: Fujitsu Siemens T4220 Lifebook_1.18_Fuj21_.rar wwwDOTsendspace.com/file/gd1ti7 While flashing the file in Windows 7, I received the following ERROR:cannot flash if memory managers (e.g EMM386) present This presumably means that I need to flash the BIOS using CD or Flash Drive in DOS mode. Below is the following file structure for the Fujitsu Siemens T4220 Lifebook_1.18_Fuj21_.rar: DOS File folder FUJITSU-FUJ-2.0-XrML Digital License Then under DOS File folder are the following files: autoexec.bat COMMDAND flash.bat KERNEL.SYS MORE phlash PLATFORM README.bat readme.txt SRTV118.ROM SRTV118.ROM.BAK I have not flashed the using CD nor USB drive. Do I just take the image of the expanded folder Fujitsu Siemens T4220 Lifebook_1.18_Fuj21_ and copy the image onto a CD disc or USB drive? Then just reboot from the CD/USB drive. If so, what would I need to type in terms of command line to flash or would the flash be done automatically during the reboot? Do I need additional files to boot and flash the BIOS? I prefer to try flash the CD with a USB drive. I looked at both wwwDOTbootdisk.com rufusDOTakeo.ie and still a bit confused. Do I make the USB drive bootable using the tool then put the files for Fujitsu Siemens T4220 Lifebook_1.18_Fuj21_ into the bootable drive and let it boot automatically? Sorry I am a newbies and never done this. Thanks for your help in advance. IF I posted in the wrong thread, please forward to correct section. Thank you.
