DFI UT X58-T3EH8 continued - Part 2

[ph0b0s]

Sorry if this has been asked before but due to DFI's bios naming convension (or lack of) this is difficult to search for. Just updated my LANPARTY UT X58-T3eH8 motherboard with the bios 06/19 / LX58D619.bin (not beta). After this upgrade, whenever I tell Vista to restart, press crtl + alt + del at boot or exit the bios, the whole system will power off for 4 - 5 seconds. Then the power restarts and the system boots.

I assume that this is part of the bios upgrade, but just want to check that others are seeing the same thing when using the same bios. Before the upgrade the motherboard appears to be powered even during restarts, bios changes etc. The only time I had seen this before was when changing the JMB363 controler bios setting from 'enabled' to 'disabled'.

At the moment the bios is set to all default settings and gives the same behaviour.

Anyway, anyone else getting this?
