Setup Utilities and Diagnostics Features Heading Option Description Advanced* (continued) *For advanced users only Power-On Options (continued) Allows you to set: (continued) • Hyper-threading (enable/disable) • Set Up Browse Mode (enable/disable). Enabling this feature permits Computer Setup to be viewed, but not changed, without entering the setup password. • Limit CPUID Maximum Value to 3 - Restricts the number of CPUID functions reported by the microprocessor. Enable this feature if booting to WinNT. • 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. Execute Memory Test Restarts the computer and executes the POST memory test. 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). 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. PCI VGA Configuration Displayed only if there are multiple PCI video adapters in the system. Allows you to specify which VGA controller will be the "boot" or primary VGA controller. Bus Options On some models, allows you to enable or disable: • PCI SERR# Generation. • PCI VGA palette snooping, which sets the VGA palette snooping bit in PCI configuration space; only needed when more than one graphics controller is installed. ✎ Support for specific Computer Setup options may vary depending on the hardware configuration. 2-12 390812-001 Service Reference Guide, dx7200
