[. . . ] · S3 (STR) (Suspend To RAM): In this method, the processor does not execute instructions. The state and content of the processor's internal registers is stored in RAM along with the 58 dynamic context of the memory. Information about devices qualified as suitable to be woken up from hibernation is also stored in RAM. When a waking up event occurs, the devices that can wake up the system restore the contents of the registers of the processor from RAM and force all the peripherals to be relinked. Run VGABIOS if S3 Resume Selects whether to run the VGA BIOS if resumed from S3 state. This is only necessary for older VGA drivers. · Auto · Yes · No Note: This option is enabled only if S3 or S1 & S3 is selected from the ACPI Suspend Type option. 59 3. 7. 1 PCI Express PM Function PCI Express components are permitted to wakeup the system using a wakeup mechanism followed by a power management event (PME) Message. PCI Express systems may provide the optional auxiliary power supply (Vaux) needed for wakeup operation from states where the main power supplies are off. PCI Express-PM extends beyond the PME mechanism defined in conventional PCI-PM as PCI Express PME Messages include the Requestor ID of the requesting agent. These PME Messages are in-band TLPs routed from the requesting device towards the Root Complex. PCI Express PME This option performs the same function as Wake-Up by PCI card, but is for PCIExpress cards. · Enabled · Disabled 60 3. 8 PnP/PCI Configurations This section allows configuring PnP / PCI resources. Reset Configuration Data If you install a new piece of hardware or modify your computer's hardware configuration, the BIOS will automatically detect the changes and reconfigure the ESCD (Extended System Configuration Data). Therefore, there is usually no need to manually force the BIOS to reconfigure the ESCD. However, the occasion may arise where the BIOS may not be able to detect the hardware changes. A serious resource conflict may occur and the operating system may not even boot as a result. This is where the Reset Configuration Data BIOS feature comes in. This BIOS feature allows you to manually force the BIOS to clear the previously saved ESCD data and reconfigure the settings. All you need to do is enable this BIOS feature and then reboot your computer. The new ESCD should resolve the conflict and allow the operating system to load normally. Please note that the BIOS will automatically reset it to the default setting of Disabled after reconfiguring the new ESCD. So, there is no need for you to manually disable this feature after rebooting · Enabled · Disabled When this option is set to AUTO, the BIOS by using ESCD, controls the IRQ and DMA assignments of all of the boot and PNP devices in the system. If you set this option to Manual, you will be able to manually assign all IRQ and DMA information. · Auto (ESCD) · Manual 61 PCI / VGA Palette Snoop This option is only useful if you use an MPEG card or an add-on card that makes use of the graphics card's Feature Connector. [. . . ] PCI card that allows a RAID card to use the onboard SCSI chip, thus lowering cost of RAID solution ZIF Socket (Zero Insertion Force socket): these sockets make it possible to insert CPUs without damaging the sensitive CPU pins. The CPU is lightly placed in an open ZIF socket, and a lever is pulled down. This shift the processor over and down, guiding into the board and locking it into place. 83 NOTE 84 Technical Support If a problem arises with your system, you should turn to your dealer for help first. Your system has most likely been configured by them, and they should have the best idea of what hardware and software your system contains. [. . . ]
