Has anyone modified a bios from a sony vaio notebook? I've been trying to backup a copy of the current bios to modify it, or to request someone with more experience to modify it, but haven't had any luck yet. I've tried running a copy of phlash from a bootable usb stick, but it says it won't run if any memory managers (eg HIMEM.sys) are active. Winphlash64 hasn't worked for me either, giving me error103 - seems i can't backup the bios without a proper replacement bios in the new bios field. haven't been able to locate a copy of the bios online either. The laptop is model VGN-NR498D. The bios is a phoenix technologies R2060J9. currently running vista64 ulitmate. thanks for any help!
