BIOS archive for an HCL machine labelled N-VIDIYA, which most likely refers to a board variant with an NVIDIA chipset or graphics; the name says nothing more. Revision and version details are missing, so review the files inside the 1.74 MB RAR before relying on them. The usual use is reprogramming the SPI or LPC firmware chip with a programmer to fix a dead or looping board. Back up the original chip, compare its capacity with the image size, and check that the board markings agree.
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 @afsbiosfree. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
