Computer Setup (F10) Utility Computer Setup (Continued) Heading Option Advanced* (continued) Power-On Options (continued) *For advanced users only. Description Allows you to set: • I/O APIC Mode (enable/disable). Enabling this feature will allow Microsoft Windows Operating Systems 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 is that some amount of memory below 1 MB is freed up for use by option ROMs. 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 MB or less of RAM. • Hyper-threading (enable/disable). • Limit CPUID Maximum Value to 3 Restricts the number of CPUID functions reported by the microprocessor. Enable this feature if booting to WinNT. BIOS Power-On Allows you to set the computer to turn on automatically at a time you specify. Onboard Devices Allows you to set resources for or disable onboard system devices (diskette controller, serial port, or parallel port). ✎ Support for specific Computer Setup options may vary depending on the hardware configuration. 20 www.hp.com Computer Setup (F10) Utility Guide
