Archive for the Intel D425KT, an Intel Atom D425 based mini-ITX desktop board. The RAR is 677 KB and the name carries no version or revision details. It most likely contains a BIOS image intended for rewriting the onboard flash when the board fails to boot. Technicians program such files with an external flash programmer. Confirm the board identification label matches this model, read and store the original chip contents first, and check the image size against the flash capacity before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @hrtechno. Enginerys does not host this file.
