Software Installation

DOS Driver Install
The INSTALL4.EXE utility can install DOS device driver automatically. If you want to install DOS device driver manually, please follow the steps below.

1. Copy the driver UM8672. SYS into the appropriate path.

2. Add the following statement to file CONFIG.SYS
   DEVICE=[ drive] [\path] UM8672. SYS [/D] Where D is Driven speed m(0-11) (0 is the lowest) (See Appendix A for Reference)

3. Save the CONFIG.SYS and reboot your system
   Remark : You don’t need to specify drive speed parameters usually, because the device driver is reconfigured for the optimal speed setting

Microsoft Windows 3.x Driver Install

The INSTALL4.EXE utility can install Windows device driver automatically. If you want to install device driver for your system manually, please follow the steps below. You are advised to make a copy of SYSTEM.IN! before Driver installation.

1. Copy the UM8672.386 and INT13.386 into the appropriate path.

2. Check if the following lines exist in the [386Enh] section of your Windows’s SYSTEM.IN! file [386 Enh]

3. 2BitDiskAccess=ON

4. lf32BitDiskAccess=OFF, please set 32BitDiskAccess=ON
   Remark : Some software cannot support this feature, please set the parameter to OFF.

5. Add the following command line in the [386Enh] section of the SYSTEM.IN! file. device=[drive:] [\path\] UM8672.386 device=[drive:] [\path\] INT13.386

6. Delete the “device=wdctrl” and “device=intl3” setting ifit exists.

TroubleShooting Guide

No display after power on
The card have not inserted in the slot correctly .
If the gold fingers of the VL-Bus dirty, it may be influenced the conduction between gold fingers and slot. The solution is to clean the gold fingers by freon or eraser.

Cannot boot up from HDD
Check the connection ofHDD cable
Make sure the HD type is set correctly in BIOS setup

If the gold fingers of the VL-Bus dirty, it may be influenced the conduction between gold fingers and slot. The solution is to clean the gold fingers by freon or eraser.

Malfunction of 1/0 ports

Check the connection of cables
Check the jumper setting of the respected 1/0 port
Check the setting in the software switch( see section 3. 0c)

Malfunction of 1/0 ports

• Check the connection of cables
• Check the jumper setting of the respected I/0 port
• Check the setting in the software switch(see section 3.0c)

Appendix A

The PT-627’s driver will set the IDE CD-ROM as the last drive even you set it as drive Dor drive E. For example,

How to use four HDDs
If the system BIOS cannot support 4 IDE devices,

• Set the jumper of the two HDDs which are connected to the primary IDE port to Master and Slave respectively, don’t care the HDDs in secondary IDE port
• Install the PT-627 driver into the boot up drive
  Drive 0| Drive 1| Drive 2| Drive 3
  ---|---|---|---
  HDD| CD-ROM| HDD| HDD
  C:| F:| D:| E:
• Then the four HDDs can be detected by the driver automatically

If the system BIOS support 4 IDE devices,
Use the above method or setup the HDDs from system BIOS directly

How to use HDD over 528MB

• Enable the LBA feature in system BIOS
• Install the PT-627 driver into the boot up drive

Remark:

• The PT-627’s driver will set the IDE CD-ROM as the last drive even you set it as drive Dor drive E. For example, Primarv
• Some software cannot support 32bitDiskAccess under Windows environment, you need to set the parameter of32bitDiskAccess=OFF(see section 3.0b)
