Chapter 4 Updating the Flash PROM on the Ultra 1, Ultra 2, Ultra 450, and Sun Enterprise 450 Systems 77
Location of Flash PROM Jumpers in Sun
Enterprise 450 System and the Ultra 450
Workstation
The flash PROM update procedure for the Sun Enterprise 450 and the Ultra 450
systems assumes that the write-protect/enable jumper was set in the default
position (enabled). In order to update the flash PROM, you must move the write-
protect/enable jumper to the write-enable position.
Three jumpers on the main logic board affect flash PROM operation.
FIGURE 4-7
shows the jumper locations, and
TABLE 4-6
describes their functions.
