ECS Golden Board Z77H2-AX Z77 Motherboard Review
ECS included their latest version of a customized AMI-developed UEFI (Unified Extensible Firmware Interface) style BIOS. The UEFI BIOS offers full keyboard and mouse support while using the BIOS pages. By default, the user sees the Basic Mode screen when entering the BIOS with the Advanced mode screens accessible via the Advanced button at the right side of the screen.
Having never used or seen ECS' implementation of a UEFI BIOS, I was mostly impressed with what I saw. The BIOS worked well with both keyboard and mouse input in most cases. However, the mouse input seemed slightly laggy with latency apparent at times when moving the mouse or clicking areas within the BIOS interface. Also, some of the menu links were very particular about where to click to open the linked screen. You had to click towards the left or upper left side of the link for the click to register. This behavior was seen with both menu links and buttons inside verification windows from within the BIOS. I was also disappointed by the fact that no in-BIOS flash update ability was integrated into the design.
