Lenovo firmware archive for a mainboard with project code VIUX1, board number NM-A091, revision 1.0, with a date of 2013-04-17 carried in the name. The NM-xxxx pattern is used by LCFC, the Lenovo-owned ODM, and by Compal for Lenovo projects. At 5.78 MB the RAR likely holds a full SPI image suitable for reprogramming with a CH341A or similar tool. Confirm the board label and revision before writing, and save the original chip contents, since that dump may hold serial and licence data worth keeping.
