Hello all,
It has been several months since I installed DD-WRT on my firewall PC, Intel U300 based, 6 10G Intel 226 ports. I don't know what file to use to upgrade it.

I can't remember it if was EFI, 2GB or EXT4.
I do know it was FUll, VGA though.

Is there a way I can determine what file I originally flashed it with?

I do have a linux based PC that I can check the actual SSD in.

The different files have confused the hell out of me too at first.

If your running this on a PC with uEFI BIOS turn off secure boot in BIOS. I would stick with the EXT4 files. I seen reports where people didn't have luck upgrading the older builds to when they implented the EXT4 and other filesystem types.

Use the RAW file here. I use the EXT4 dd-wrt_x64_full_vga-ext4.image.gz

Then updates go to the web releases https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2026/06-03-2026-r65291/x86-64/web/


Use can use RUFUS to make the boot drive for DD-WRT or even Physdiskwrite if needed. I would even write down or screenshot or take pictures of your current settings since trying to load a old configuration might make it fail to boot or other weird issues crop up.
