I have a DE45EK I'm using as a controller for an unraid system. This system boots from a usb drive which contains the OS (linux variant). The system has been functioning fine except for booting. Booting has always worked like this:
1-2 second then it displays the boot screen. The status ID in the lower right corner shows 51.
1-2 second delay then the status ID shows 51 and the F2 setup prompt displays.
system sits there for ~30 seconds. If I press F2 nothing happens.
After 30 seconds it boots. If I pressed F2 (usually takes several presses in the 30 second dead zone) it will display the setup screen (about half the time it doesn't and I have to reboot and try again for the setup screen).
OS boots up w/o a problem.
The system has a hard drive but this is for the unraid data and does not contain a boot partition.
There is a Sans Digital JBOD box connected that is controlled via a PCIe port multiplier card installed in the DQ45EK.
2GB memory installed (800Mhz)
Bios set to Optimal Defaults and then the following changes made:
Boot Config - F10 disabled
Peripheral Config -serial and audio disabled
Power - After Power Failure=Last State
Boot - Priority=Floppy/Hard Disk
Boot = Boot to optical drives=disabled
Boot=Boot to removable drives=Enabled
Boot=Boot to network=disable
Boot-Boot USB Devices First=Enable
Boot-USB Mass Storage emulation type=Auto
I've tried various combinations of ZIP Emulations and USB Emulation type. Nothing seems to make a difference. Will this board boot in a reasonable amount of time from a USB drive and if so, what's the magic combination?
