A PC modder, "kryptonfly," used Claude AI-assisted BIOS rewriting to inject missing microcode and get Intel's OEM-only Core 9-273PQE Bartlett Lake CPU to reach POST on an Asus Z790 motherboard, with the BIOS correctly identifying the processor. The system still fails to boot past POST with a black screen and errors, underscoring that full Bartlett Lake support remains unofficial and could be closed off by future Intel or Asus firmware updates.
