Latest Modded BIOS for T-420 and T-520 (and W-520)

#1 Post by wsalomon » Sun Aug 16, 2020 12:16 am

I'm a previous user of modded BIOS for T-420 (1.51 (83UJ32US)) and T-520 (1.48 (8AUJ29US)) which had the white list removed and displayed the Advanced BIOS settings. These have worked wonderfully well. (Full 16 GB RAM, Optimus NVS 4200, glossy AUO screens which are crystal clear) updated WiFi with latest drivers for Win 10 2004)

Unfortunately, one of my T-520s lost a motherboard, and I accidentally ordered a W-520 motherboard with the Quadro 2000 GPU by mistake. It does fit the T-520 frame, and will take 32 GB of RAM instead of 16 GB (which works for me, although it needs a different fan/heatsink, DC power socket and a 170 W power supply), so...

I've decided to keep it *IF* I can find a W-520 modded 1.46 (8BUJ25US) BIOS mentioned elsewhere at http://rgho.st/8JBjMm4mn (which appears to have had the file removed).

Were the T-420 1.52 (83UJ33US) and T-520 1.49 (8AUJ30US) BIOS available as well, I would be interested in those too to update my other systems.

If anyone has information on what the Advanced BIOS options are (more than just going into the BIOS and looking at the brief, but at times not too helpful, descriptions, I'd be interested in that as well.

My thanks in advance for any leads on this.
