What do you mean with "clean"?

I will now focus on the 2.07, it seems to work fine and since it's possible to flash the stock version I only have to mod one file, that is a big time saver.

Is it possible to update the BIOS from 1.xx to the 2.xx or 3.xx?

Y410P can work well on OS X Mavericks now except the Nvidia GPU and intel Wireless card.

sorry to hear that

for recovery flashing, neither.

I ran out of ideas, maybe svl7 can help you somehow...

Thank you so much, I have the BIOS chip programmed with a flashrom programmer!

what was your backup bios file name on the usb stick?

bios.bin will not work, you have to rename it like the article said:

2.3. Download andy's tool for identifying the correct filename of the BIOS for recovery (andy's tool)

2.4. Load the *.ROM file with andy's tool. A Message box will popup. It will show a filename you should use.

2.5. For me the file was called "QIWY.bi?". I formatted a usb flash drive (1GB) with a FAT filesystem (FAT32 should work fine as well) and put a few copies of the QIWY3207.ROM file on the drive. I used some variations of the filename because the character "?" is not allowed in filenames. So it put *.bi, *.bin, *.ROM and *.fd on the drive (don't know which one acutally worked).

I used a 256m usb flash disk, and tried the file name Yx01.bin, .rom, .wph, .fd, but none worked.

need I use crysis tool (wincris.exe) to prepare a bootable disk or remove other HD disks?

svl7, is flashing a bios by default overwriting the variable area, or you have to force it by parameters?

If yes, you should try making an auto flash usb stick, remove hdd, and boot machine like that.

Or try the emergency flash method in the linked article?

If the RAM doesn't have XMP profiles then the bios won't change anything regarding this.

Maybe? You should know what you did....

Did not tried it myself, but it could help you.

thanks, I have tried several times, but it still boots with no display, just cpu and fans are working.

maybe I changed the igpu memory size, now i just want to boot normally and could enter the BIOS Setup first!

I used the tool to flash my Y410p BIOS and enter the BIOS Setup, when I "exit saving changes", my pc rebooted with only black screen, how can I recovey the orginal BIOS?
