Hi, I've found some great advice on here, but still having issues. Can anybody help please? Toshiba Satellite L500-19X PSLS0E with corrupt BIOS, after failed WINFLASH attempt. Blank screen on power on, with no boot. I downloaded Crisis disk. Downloaded latest PLASH16.EXE I downloaded Toshiba BIOS file from Toshiba site. Extracted the BIOS210.exe file to get swaa210a.rom Renamed swaa210a.rom to BIOS.WPH I could not create Crisis floppy as the BIOS file was too big, even when trying the compressed option. I created crisis USB instead. Followed instruction, all devices removed, power removed, battery removed. Inserted USB drive, held down FN-F, inserted power & pressed power on. The USB flashes once, then nothing more. I tried both USB ports. No difference. I tried 2 other USB flash drives, still no difference. I tried creating a bootable Crisis CD. I created an IMA image from a crisis floppy, added the PLASH16.exe, MINIDOS.SYS, BIOS.WPH, then created a bootable CD. Inserted new Crisis CD & followed same instructions, to no avail. I tried all of the above again, renaming the BIOS file to BIOS.FD, to no avail. I tried using different versions of PHLASH16, to no avail. I tried using different keys (Win-B, FN-ESC, WIN-ESC, WIN-F, FN-B, FN-F), to no avail. Does anybody have any new suggestions, or can see any obvious school-boy error in what I've been trying please?
