Chapter 8. IBM BladeCenter HX5 399
A simple step to reduce the overall system start-up time is to remove any unnecessary boot
devices from the boot order list. In particular, ensure that PXE network boot is removed from
the boot order list if it is not used. PXE network boot can increase start-up time substantially,
especially if it is also placed in the incorrect order in the boot order list.
Use the following steps to remove entries from the Boot Order menu and configure the correct
boot order:
1. Log in to the Advanced Management Module and select Blade Tasks ï‚® Remote
Control. Click Start Remote Control and select the blade that you want to control from
the blade selection pull-down box.
1. Power on the system using the power control feature on the remote control, and press F1
when the UEFI splash panel displays, as shown in Figure 8-31 on page 396.
2. Navigate to the Boot Manager menu by selecting it from the System Configuration and
Boot Management main menu. The Boot Manager displays, as shown in Figure 8-33.
