H3C R4900 G3: Match Custom BIOS Preparation to CPU Generation

This is a project-specific R4900G3 motherboard-replacement note, not a generic cross-generation firmware-flashing guide. The source refers to customized “microcode,” but its examples show matching BIOS/firmware preparation for the CPU actually installed.

Check before preparing the replacement

1. Identify the customer system’s actual CPU model/generation. The source examples are 4110 for the first generation and 8255C for the second.
2. Use the correct authorized customization package/tool and preparation platform for that customer configuration.
3. Validate POST with the intended supported CPU configuration before dispatching the replacement motherboard.

Source first-generation preparation example

The source version is C35-1.00.56 V100R001B01D056, with approximately 56% progress and a DIMM/invalid-memory-configuration halt. In this case, a board prepared on the first-generation platform did not pass initialization with the customer’s 8255C configuration.

Source second-generation preparation example

The second photo shows the visible suffix -2.00.52P21 V100R001B02D052SP21 and 99% progress. Its left edge is cropped; no missing prefix is invented. It illustrates later initialization progress, not proof that every subsequent OS/hardware test completed.

Both images are English localization illustrations of the source annotations. They preserve the photographed version strings/progress and distinction between the two examples. No exact public English notice for this customized Tencent configuration was found; confirm the project-specific package, board revision and CPU compatibility with the vendor rather than using these old example versions as a current download recommendation.
