I have a W530 would like the BIOS modified on. I have read both chips with programmer, however, not sure if I am doing this correctly. The Left chip comes up as a MX25L6405D which is the 8MB chip, however the right chip which I believe is supposed to be the 4MB BIOS chip, comes up as a 16mb chip an MX25L12805D 16MB chip everytime.
Has anyone encountered this?

Hi
This laptop model has two bios chips...MX25L6405 (8Mb) and MX25L3205 (4Mb)
You need MX25L3205 only

It appears mine has a MX25L12805D 16mb instead of 3205 4mb. The 6405 chip I have identified it's 8Mb
I would like to have the following modification to my BIOS:
- WiFi Whitelist removal
- Battery Whitelist removal
- Advanced BIOS manual
I have attached my bios(4Mb) file here: https://drive.google.com/open?id=19S3YHi...MbEddOeuQi
Please let me if the 8Mb bios file is required.
Thank you very much for your help,

I'd like to get the whitelist removed from this BIOS, and also "advanced BIOS menu" if that exists for this machine. I have a programmer, and read the BIOS from the chip. Attached is the data from the 4M chip (can supply 8M data too if needed). Will donate to site or individual, just let me know paypal addr.
BTW, if anyone wants help reading/writing these chips without breaking the whole system down, I learned how to do it the easy way (after doing it the hard way). The 8M and 4M chips share all connections (pins 2 through 8) except for pin 1 (/CS). So you can access both chips by putting your clip on the 8M chip, which is accessible without removing the MB. Connect pin 1 on the chip you want to access to the clip's pin 1, and connect pin 1 on the other chip through a 10k ohm resistor to Vcc (clip's pin 8).
Thanks!

Hi, A quick/dirty guild for this would be great, and I would also like to get my bios wifi white list sorted and a advanced menu would also be great.
Thanks
