Setup Utilities and Diagnostics Features Heading Option Description Advanced** (continued) Power-On Options (continued) Allows you to set: (continued) POST Delay (in seconds) (enable/disable). Enabling this feature will add a user-specified delay to the POST process. This delay is sometimes needed for hard disks on some PCI cards that spin up very slowly; so slowly that they are not ready to boot by the time POST is finished. The POST delay also gives you more time to select F10 to enter Computer (F10) Setup. I/O APIC Mode (enable/disable). Enabling this feature will allow Microsoft Windows Operating system to run optimally. This feature must be disabled for certain non-Microsoft Operating Systems to work properly. ACPI/USB Buffers @ Top of Memory (enable/disable). Enabling this feature places USB memory buffers at the top of memory. The advantage of remapping is that it allows space in the DOS Compatibility Hole range, below 1MB, to be made available for additional PCI plug-in cards that need option ROM space. The disadvantage is that a popular memory manager, HIMEM.SYS, does not work properly when USB buffers are at top of memory AND the system has 64 KB or less of RAM. NIC Option ROM Download (enable/disable). The BIOS contains an embedded NIC option ROM to allow the unit to boot through the network to a PXE server. This is typically used to download a corporate image to a hard drive. The NIC option ROM takes up memory space below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This space is limited. This F10 option will allow users to disable the downloading of this embedded NIC option ROM thus giving more DCH space for additional PCI cards which may need option ROM space. The default will be to have the NIC option ROM enabled. Hot-Pluggable MultiBay Floppy* (enable/disable). Enabling this feature allows you to hot-plug a MultiBay floppy into a system running Windows 2000 or XP. Onboard Devices Allows you to set resources for or disable onboard system devices (serial port, parallel port, or diskette controller). PCI Devices Lists currently installed PCI devices and their IRQ settings. Allows you to reconfigure IRQ settings for these devices or to disable them entirely. These settings have no effect under an APIC-based operating system. * Available on select models. **These options should be used by advanced users only. Service Reference Guide, d500 336492-005 2-11
