Sourcing Replacement BIOS Chip within UK - GigaDevice 25R256DYIG

[CapThatBrass]

Hi,

I'm trying to source a replacement BIOS chip for a Dell laptop, the current one being a GigaDevice (AJ2144) 25R256DYIG. Its a WSON8 8x6 package.

I'm struggling to find this chip within the UK.

Does anyone know where I can source one from? If not this model, a possible alternative is a Winbond 25R256JVEN but again I'm struggling to find this one within the UK,

Any help would be great.

Thanks
