Hello everyone, I just replaced the bios chip on my laptop because the one I had got corrupted. I was wondering if anyone has the bin files to the GA503RM so that I could flash the new Bios chip? Thanks in advance!!

Re: need BIOS for ASUS Zephyrus GA503RM
Its not the only chip on the board.That one is 2MB, you can`t fit a 32MB bios into it. That chip is for firmware,could be for the vBios,USB4 firmware,thunderbolt or whatever, but it aint the bios chip
.I hope you havn`t erased that 2MB chip,and if you did i hope you made a backup first or you`re in big doo-doo

Got it. Can't really find another chip that looks like that so I assumed it was the BIOS chip.Comment

Re: need BIOS for ASUS Zephyrus GA503RM
First of all tell us what the problem is with your laptop? Corrupted bios or it's just password locked and you are trying to remove the password by programming clean bios?
Maybe you didn't know but there's many different (visually too) SPI NOR flash memory chips, not only the traditional SOIC-8 type as in your picture, like SOIC-16, DIP-8, WSON-8 (8x6), WSON-8 (6x5) and so on.
Most probably the bios chip in your laptop is WSON-8 (8x6):
Edit: Yes, it's certainly WSON-8 (8x6):

Re: need BIOS for ASUS Zephyrus GA503RM
Can anyone help me with the PDF file of it8252e248a? My Asus GA503RM cannot use the keyboard and keyboard light. I found a website that has a PDF of the it8252e248a and its firmware. However I cannot download it. Can I post a link here to get help?Comment

Re: need BIOS for ASUS Zephyrus GA503RM
Didn't turn on for me with this file. Original bios turns on no display then after a while shuts off then turns on again.

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Hello,
I have spent the last hour on this and I guess this is just over my head, so here I am.
I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.
The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.
Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website... -
I’m troubleshooting an ASUS ROG Strix B660-I Gaming WiFi motherboard and I’m a bit stuck at the BIOS level. What I’ve tried so far- Attempted to flash the BIOS using the USB BIOS FlashBack (Q-Flash) port with a properly formatted FAT32 USB drive.
- BIOS file downloaded directly from the official ASUS support page.
- Followed the exact FlashBack procedure (correct port, renamed file, standby power only).
Issue:
The FlashBack LED does not blink at all — no activity whatsoever. Further investigation
