Setup
When you want to enter the BIOS Setup, you have to press the keyboard ‘DEL’
key at the right moment. Especially when using a slow starting monitor it might
be too late to wait for the CRT to show the message ‘Press DEL to enter Setup’.
Better look for the LED and press ‘DEL’ as soon as the LED goes from amber
to green blinking. When you are using add on cards with external BIOS, you
can hit the DEL key while their BIOS runs.
When you miss the right moment to press the DEL key, please use the reset
button on the front panel to restart the power up sequence or switch off the
power supply for a few seconds and restart it.
Unexpected Resets
Whenever the VR11 unexpectedly issues a reset and starts booting again, you
may want to know the reset source. For this reason a set of special registers is
implemented onboard. Every reset source set there a special bit and can be read
in the next boot up. The register description can be found in the ‘Board Specific
Hardware Programmer’s Manual’.
