Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.
I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For... -
hey all, i did a silly thing and flashed bios to perfectly working board. None of the asus official download bios would work with ez flash. They all gave error saying not supported bios file. I tried using uefi tool to extract it to a bin file but then ez flash wouldnt even recognise it.
So, i used freedos and afudos with the aforementioned bin file i extracted and forced the issue. After bios reprogram, reboot and it was dead. Fans spinning but no post.
i have a bios writer and none of the .cap files from the official site work either. I just get one spin, then off, then all fans...10-17-2024, 02:53 AM -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hi,
I have a serious problem to program the Z590 chipset SRAM with a Management Engine after replacing the chipset.
The new chipset is factory new and is not containing any Management Engine. Any attempts to program it into the chipset under Windows ends with a failure (eg. Error 20: Management Engine Device not present, or something similar).
Due to the lack of the ME several ports on the board, including all M.2 ports aren't working, booting OS works only on USB. So it's now other way, as to program the chipset with a ME.
Usually on ASUS boards it worked... -
Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
