Toshiba C655D-S5300 (PSC0YU)

[AugustStorm]

Hi,

I flashed a custom BIOS to see if I can get virtualization turned on.  The flash went successful and I can access the bios settings.  The problem I have is I cannot boot into any windows even a Windows XP boot CD.  I can boot to a FreeDOS USB Drive so I figured I can run the flash from there.  All the flash utilities require windows, so I tried FLashIt and I get the dreaded "FADT not found!" error.  I assume ACPI related per other threads

(see https://www.bios-mods.com/forum/Thread-U...Semi-Brick)


I have tried various combinations to get the laptop to boot into crisis mode without success.  I have tried combinations of the Fn or Windows Keys and B, W, Esc, R, F, End, and maybe some others.  I have even tried the combinations with holding down the power button prior to pluggin in the power cord.  However it never even seems to power on, that is I see the power connect LED light up but the laptop never starts and illuminates the power on led.  The fan doesn't start...nothing.

Has someone ever gotten this laptop to flash after the FADT error?  is there another way I can flash this?  Anyone ever successfully enter crisis mode and get it to flash?

Thank you.
