Invalid ROM based on bad
checksum.
System powers on but does
not start.
Recommended action
CAUTION: Internal components might be powered even when the
workstation is off. To prevent damage, disconnect the workstation power
cord before you remove a component.
1. Clear CMOS.
NOTE: Refer to the Maintenance and Service Guide for the
workstation model for detailed information on clearing CMOS.
2. Upgrade the ROM using SoftPaq, either from the hard drive, CD,
diskette, or USB removable device (for example., HP Drive Key).
See the ROM Flash section of the Maintenance and Service
Guide at http://www.hp.com/support/workstation_manuals. SoftPaq
is a self-extracting executable, which contains instructions for its
use, that enables you to upgrade the ROM. To download the Softpaq
executable, visit http://www.hp.com/go/workstationsupport.
