Fpr-24363.ic48 Awbios May 2026

In the target hardware schematic, IC48 functions as the Primary SPI Flash Controller interface (or a secondary backup power gate). It is responsible for delivering the firmware volume to the CPU during the reset vector. Due to recent hardware revisions increasing the density of the SPI Flash (moving from 16MB to 32MB configurations), signal integrity issues have been observed during the transition from the PEI to the DXE (Driver Execution Environment) phase.

Updating AWBIOS involves several steps, which generally include: fpr-24363.ic48 awbios
