    Hey all, I recently found out about bios modding and decided to give it try on my own. However, as I lack experience, I am unable to find exact instructions on how to carry a bios mod out. My BIOS is the Insyde H20 F.53. I would like to unlock the advanced options tab which I see in other modded Insyde BIOSes but from my knowledge HP has disabled that and I am unable to find a way to enable that. Can anyone help me by providing a guide on how to mod the BIOS or help me mod it which would be great since I'm a newbie to BIOS modding:). Thanks and looking forward to a positive response[​IMG]! I can't upload the BIOS here as its too big, so I'm leaving a link:)

    ps.@Prema I heard that you are really good at this so could you help me?

    You would want to purchase a flash programmer like the ch341a, use the hp service manual to disassemble the machine far enough to find the bios chip. Dump the contents of the chip using the programmer, then post the dump to the bios-mods forum offering a small donation if someone will unlock it for you. Then you can simply take the unlocked bios and flash it to the chip and put your machine back together. Another good one to look at is the win-raid forums that have good guides on doing the mod yourself. Not that the tools to do modding are sometimes not easily available so it may be easier to have someone unlock it for you for a small donation.

    In certain cases like the MSI WT75 the bios lets you turn off write protection to the flash area temporarily so it's possible to flash modded bioses via the Intel FPT toolset. However for most all major manufacturers like Dell and HP since 2014 this has not been possible making the disassembly and manual chip programming necessary. The mobile Pascal tdp tweaker thread is a good reference here because it's a similar process, just targeting the GPU bios instead of system bios.
