You can take a coffee break while waiting for the DL580 Gen8 to boot. In our testing and rebooting, it took seven minutes. Should you use the supplied front panel or rear panel connections to a crash cart/console, the system boots to numerous options, including a rudimentary GUI. Function key selections permit alternate boots, although we use PxE, which worked well. The BIOS suits UEFI boots, but it can be disabled to accommodate OS installations that don’t want the draconian controls of UEFI.
