I was upgrading the BIOS on this model Toshiba (PSPMHA-01600L) in Win8.1 today from v1.0 to v1.9. Three quarters of the way through writing the FLASH the laptop shut down. AC mains was in and definitely on. Never in my life of flashing BIOSes has this crap happened.
Here are my options in order of preference:
A) Someone here can reveal to that that putting say FW.BIN on an MSDOS-16 USB stick and pressing CTRLB at poweron will fix everything (or something like this).
B) I can locate the flash chip, desolder it and JTAG the binary in. (I can do this).
C) Buy a new motherboard.
I'd really love A to happen. Does anyone have advice on this matter?
The BIOS file archive in question is this:
http://www.mytoshiba.com.au/file/downloa...s_w190.exe
7ZIP doesn't show any obvious .fd or .bin files in winflash.exe but the UNIX command 'strings' shows there is likely a BIOS in here.
Here are the files in that archive:
7,789 fparts.txt
1,326,552 fptw.exe
237,528 FWUpdLcl.exe
65,536 idrvdll.DLL
1,560,576 ME_FW.BIN
18,432 ModelName.exe
118,784 pmxdll.DLL
119 UBIOS.BAT
5,758,976 winflash.exe
Any help would be greatly appreciated!
