Recent posts by Twitter user Momomo_us have revealed a BIOS firmware upgrade for the AsRock Intel chipset motherboard. 

Additionally, the online community has discerned a discreet update by ASUS for a more advanced model. These motherboards both utilize the LGA 1700 socket platform and presently support Intel's 13th Gen Raptor Lake CPU series. Nonetheless, details discovered on the ROG Maximus Z790 APEX and B760M PG Sonic WiFi webpages imply preparation for the speculative introduction of the Raptor Lake Refresh.

BIOS update changelogs for these motherboards mention "compatibility for the next-gen" and "support for next-generation" processors, suggesting their preparedness for imminent CPU releases. TPU community member Nater has remarked that the ASUS ProArt Z790-CREATOR WIFI board is also set to support the 14th Gen processors.

Information leaks propose that the Intel 14th Gen Core lineup is set to be launched around October of this year. The Raptor Lake Refresh is expected to be an interim release, given that the desktop Meteor Lake-S SKUs are rumoured to have been withdrawn from the roadmap. A comprehensive next-generation update, named Arrow Lake-S, is not anticipated until Q4 2024 or Q1 2025.
