Introduction
1.1 ProductFeatures
1.1.1 Full Software Configurable
TIGAT-815E+S Classic motherboardseries are full software configurable.
There is no jumper or DIP switch on board and all the necessary hardware
settings are made through CMOS setup. This motherboard auto-detects the
CPU brand and core voltage, where as the CPU speed is selected in CMOS
setup menu by the instruction of users.
In addition, TIGA T-815E+S Classic motherboard series employs AMI
BIOS which provides two start-up hot keys “J”and “F”to give a way out
of stability problems due to improper CMOS settings. That is, to press “J”
key at the same time to switch on the system, which re-detects CPU brand
and allows user to select again in the CMOS setup. To press “F”key at the
same time to switch on the system clearing all CMOS settings (except BIOS
passwords).

2.4 Function & Installation Instructions
2.4.1 ATX Power Supply Connector (20-Pin)
This connector connects to an ATX power supply. The plug from ATX power
supply will only insert in one orientation because of the different hole sizes. Find
the proper orientation and push down firmly making sure that the pins are aligned.
The system power can be turned off through software control, like the shut down
in Windows 2000 / ME / 98 / 95 start menu. Power management must be enabled in
the system BIOS in order to activate this soft-off feature. Once the system BIOS
receives the power management command from the OS, it will switch the system
power off.

1. IntroduceSTRfunction:
STR (Suspend-to-RAM) is a Windows 98/2000/Me ACPI sleep mode function. When
recovering from STR (S3) sleep mode, the system is able, in just a few seconds, to retrieve the
last “state”of the system before it went to sleep and recover to that state. The “state”is
stored in memory (RAM) before the system goes to sleep. During STR sleep mode, your
system uses only enough energy to maintain critical information and system functions,
primarily the system state and the ability to recognize various “wake up”triggers or signals,
respectively.
2. STRfunctionInstallation
Please use the following steps to complete the STR function installation.
Step-By-Step Setup
Step 1:
To utilize the STR function, the system must be in Windows 98/2000/Me ACPI mode.
Putting Windows 98/2000/Me into ACPI mode is fairly easy.
Step 2:
After software setup completes, reboot your system and setup BIOS. Select the item
“POWER MANAGEMENT SETUP”, then select “ACPI Sleep Type: S3 / STR”.
Remembertosave the settingsbypressing“ESC”andchoosethe“SAVE&EXITSETUP”
option.
3. HowtoputyoursystemintoSTRmode?
There are two ways to accomplish this:
a. Choose the “Stand by”item in the “Shut Down Windows”area.

Parameter Description
Type The number for a drive with certain identification parameters.
Cylinders The number of cylinders in the disk drive.
Heads The number of heads.
Write The actual physical size of a sector gets progressively smaller as
Precompensation the track diameter diminishes. Yet each sector must still hold 512 bytes.
Writeprecompensationcircuitryontheharddiskcompensatesforthephysical
difference in sectorsize by boosting the write current for sectors on inner
tracks. This parameter is the track number on the disk surface where
write precompensation begins.
LandingZone This number is the cylinder location where the heads normally park
when the system is shut down.
Sectors The number of sectors per track. MFM drives have 17 sectors per
track. RLL drives have 26 sectors per track. ESDI drives have 34 sectors
per track. SCSI and IDE drives have even more sectors per track.
Capacity The formatted capacity of the drive is the number of heads times the
number of cylinders times the number of sectors per track times 512
(bytes per sector).
