If there is a display on the VGA port, but not on the LCD, replace the display
assembly (LCD, lamps, and cable).
If the display adapter is bad, the BIOS should report it using beep codes (see
Table 6--10, on page 6--68).
If nothing is displayed, is the display turned on? At boot time and while using an
external monitor connected to the NLX external video port, press F2 to enter the
BIOS setup. The Advanced Video Configuration menu lets you select PCI
(LCD) or AGP (the NLX port on the rear panel). The lower VGA port on the
rear panel is the PCI video port (driven by the same video controller as the
LCD).
If the oscilloscope will not boot, press F8 to enter the start up menu, and boot to
the command prompt. If you can boot to the command prompt, use the MSDOS
Edit program to edit the autoexec.bat file to run the CMOS restore utility (see
Update/Restore the NLX Board CMOS
on page 6--75).
