Programmable logic controller for Z490 motherboard
The instructions indicate Q-code A2 relates to IDE detection, suggesting a storage problem or access issue on the board. Even after attempting boot without any drives, this code appears to point to a deeper concern. It seems you're wondering if the CPU and motherboard are new—would checking the BIOS help? Since you can't perform a POST, that limits further progress. Ideally, testing another working Z490 board would clarify whether the issue lies with the remaining components (like MB swap or CPU swap). While it's not always practical for everyone, this could be the key to resolving the problem.
