Tools: Winphlash (v188.8.131.52) Bios: Official(from sony download) closely related to the one you have or: Unofficial "modded"(downloaded from other sites) Background: -I have a vaio vgn-nr series (bios R1101J9) with intel GMA(x3100)and was able to download an unofficial modded bios R1150J9 also for a vgn-nr series(nvidia chipset). -First, i backed up my bios(R1101J9) using "Univeral Bios Back up Toolkit". Size came up to 1024kb. -Then, i tried to back up using Winphlash but, as everyone who tried before have found out, it needs a copy of the original bios which i don't have! So, i used the R1150J9 since it's the closest one i found. Winphlash generated a "BIOS.BAK" in the same folder. I Checked the file size and it came to 1027kb. On a hunch, i figured the difference in size from the one generated using "Universal Back Up Tool kit" may be the missing "Platform Data" that is required to flash it. Findings: -Back ups made with "Univeral Bios BackUp toolkit" = No platform data hence can not be flashed -Back ups "successfully" made with Winphlash(BIOS.BAK) = Has platform data flashable! You do not need the original bios to do this as in my case. Your GOAL is to find a bios close enough to cause the winphlash program to generate a "BIOS.BAK". This is a mirror of your current bios and has the platform data. THAT'S THE KEY! Remember to run program as admin and choose "Backup BIOS Only". Note: Was also able to back up my bios(R1101J9) with winphlash using downloaded modded bios from VGN-fz series (R0050J7, R1120J7, R2110J7). VGN-FZ and VGN-NR series have no official bios updates! It seems like platform data is not bios specific but general and the same across closely related bioses. So my next step was to rename my back up (from winphlash) "BIOS.BAK" TO "BIOS.WPH" and use this in the Phoenix tool to add slic 2.1. Then i used winphlash to flash it back. Hope this workaround will guide some of our members to do further reserach and more insights will come in. Will provide files later if needed as they are on the other computer.
