Power-On/Off (Remote)

The EP-MVP4M has a single 20-pin connector for ATX power supplies. For ATX power supplies that support the Remote On/Off feature, this should be connected to the systems front panel for system Power On/Off button. The systems power On/Off button should be a momentary button that is normally open. The EP-MVP4M has been designed with Soft Off" functions. You can turn Off the system from one of two sources: The first is the front panel Power On/Off button, and the other is the "Soft Off" function (coming from the EP-MVP4Ms onboard circuit controller) that can be controlled by the operating system. Windows 95 will control this when the user clicks that they are ready to Shutdown the system.

Section 4 AWARD BIOS SETUP

BIOS Instructions

Awards ROM BIOS provides a built-in Setup program which allows user to modify the basic system configuration and hardware parameters. The modified data will be stored in a battery-backed CMOS, so that data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM will stay unchanged unless there is a configuration change in the system, such as hard drive replacement or a device is added. It is possible for the CMOS battery to fail, this will cause data loss in the CMOS only. If this does happen you will need to reconfigure your BIOS settings. To enter the Setup Program : Power on the computer and press the <Del> key immediately, this will bring you into the BIOS CMOS SETUP UTILITY.

EP-MVP4M 4-9 IDE HDD Auto Detection
The IDE HDD auto detection utility is a very useful tool, especially when you do not know which kind of hard disk type you are using. You can use this utility to detect the correct disk type installed in the system automatically. But now you can set HARD DISK TYPE to Auto in the STANDARD CMOS SETUP. You dont need the IDE HDD AUTO DETECTION utility. The BIOS will Auto-detect the hard disk size and model on display during POST.

Figure 10: IDE HDD Auto Detection
NOTE: HDD Modes The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NORMAL mode Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing. The maximum number of cylinders, head & sectors for NORMAL mode are. 1024, 16 & 63 no. Cylinder x no. Head x no. Sector x no. per sector (1024) ( 16) ( 63) ( 512) 528 Megabytes

Page 4-23

If user set his HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that! LBA (Logical Block Addressing) mode: A new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD. During HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder into its own physical address inside the HDD. The maximum HDD size supported by LBA mode is 8.4 GigaBytes which is obtained by the following formula: no. Cylinder x no. Head x no. Sector x bytes per sector (1024) ( 255) ( 63) ( 512) 8.4 GigaBytes
LARGE mode: Extended HDD access mode supported by Award Software. Some IDE HDDs contain more than 1024 cylinder without LBA support (in some cases, user do not want LBA). The Award BIOS provides another alternative to support these kinds of LARGE mode. CYLS HEADS SECTOR MODE NORMAL LARGE
BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by dividing it by 2. At the same time, the number of heads is multiplied by 2. A reverse transformation process will be made inside INT 12h in order to access the right HDD address! Maximum HDD size: no. Cylinder x no. Head x no. Sector x bytes per sector (1024) ( 32) ( 63) ( 512) 1 GigaByte

Page 4-24

Note: To support LBA or LARGE mode of HDDs, there must be some software involved. All the software is located in the Award HDD Service Routine (INT 13h). It may fail to access a HDD with LBA (LARGE) mode selected if you are running under an Operating System which replaces the whole INT 13h. UNIX operating systems do not support either LBA or LARGE and must utilize the Standard mode. UNIX can support drives larger than 528MB.
