Re:Can't find keyboard after bios update SZ2Z on a X58 SLI MB
Roll back your bios to 2z2x and see if the issue is gone.
Loop 1: EVGA x58 E760 i7 930, HK 3.0 cpu block, EK chipset block and dual bay res, swiftech mcp655 pump, feser x 360 rad, NZXT Sentry LXE fan controller w/kaze & panaflow 3k fans, bitspower and feser fittings galore, distilled water w/primochill liquid utopia
Loop 2: Dead and buried.
