Some non-standard VGA display cards may not show colors properly.
¥ Assign IRQ for VGA  
< Enabled >
Enables or disables VGAs IRQ assignment.
¥ OS Select for DRAM > 64MB  
< Non-OS2 >
This segment is specifically created for OS/2 when DRAM is larger than 64MB.
¥ Report No FDD for Win98/98SE/2000  
< Yes >
This option allows Windows98/98SE/2000 to share IRQ6 (assigned to a floppy disk drive) with other
peripheral in cash the drive is not existing.
¥ Video ROM BIOS Shadow

These options determine whether optional ROM will be copied t RAM by 16K byte or 32K byte per/unit.
OnBoard VGA Function
The following options allow the overriding of the VGA BIOS setting integrated in the core chipset of
SBC8360-4M.
¥ LCD Type  
< (Type 8) 800x600   TFT >
Although the system chipset already supports VGA and LCD alike, BIOS Features Setup still expands
this feature further with the option to set any of 15 LCD types.
¥ VGA Expansion (Full Screen)  
< Enabled >
This option allows you to enlarge application screens to full screen scale onto your display.
However this opton is not inversely compatible, rendering no change when applications screens have
resolutions larger than the display resolution.
¥ Display Type During POST  
< Both >
¥ Display Type After POST  < Both >
This item configures the viewing area for the POST sequence. When configured to the incorrect display
setting or BOTH, it blankets the POST sequence from being viewed. If you select Default this option
is useless and follows the VGA BIOS setting.

¥ SDRAM RAS-to-CAS Delay  < 3 >
You can select RAS-to-CAS delay in HCLKs 2 or 3. The board designer should set the values in this
field, depending on the DRAM installed. Do not change the values in this field unless you change
specifications of  the installed DRAM or installed CPU.
¥ SDRAM RAS Precharge Time  
< 3 >
When synchronous DRAM is installed, the number of clock cycles of RAS precharge time depends on
the DRAM timing. Do not reset this field from the default value specified by system designer.
¥ SDRAM CAS Latency Time  
< Auto >
You can select CAS latency time in HLCKs 2, 3 or Auto. The board designer should set the values in
this field, depending on the DRAM installed. Do not change the values in this field unless you change
specifications of  the installed DRAM or installed CPU.
¥ SDRAM Precharge Control  
< Disabled >
¥ DRAM Data Integrity Mode  < Non-ECC >
This option sets the data integrity mode of the DRAM installed in the system.
¥ System BIOS Cacheable  
< Disabled >
Selecting Enables allows caching of the system BIOS ROM at F0000h-FFFFh, resulting in better
system performance. However, if any program writes to this memory area, a system error may result.
¥ Video BIOS Cacheable  
< Disabled >
This item allows you to change the Video BIOS location from ROM to RAM. Video shadow wil increase
the video speed. 
						

							Ñ 21 Ñ
¥ Video RAM Cacheable  < Disabled >
Selecting Enabled allows caching of the Video BIOS ROM at C0000h to C7FFFh, resulting in better
video performance. However, if any program writes to this memory area, a system error may result.
¥ 8 bit I/O Recovery Time  
< 1 >
¥ 16 bit I/O Recover Time  < 1 >
The I/O recovery mechanism adds bus clock cycles between PCI-originated I/O cycles to the ISA bus.
This delay takes place because the PCI bus is so much faster than the ISA bus.
These two fields let you add recovery time (in bus clock cycles) for 16/8 - bit I/O.
¥ Memory Hole At 15M-16M  
< Disabled >
You can reserve this area of system memory for ISA adapter ROM. When this area is reserved, it
cannot be cached. He user information of peripherals that need to use this area of system memory
usually discusses their memory requirements.
¥ Passive Release  
< Enabled >
When enabled, CPU to PCI accesses are allows during passive release. Otherwise, the arbiter only
accept another PCI master access to local DRAM.
¥ Delayed Transaction  
< Disabled >
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select
Enabled to support compliance with PCI specification version 2.1.
¥ AGP Aperture Size (MB)  
< 64 >
The field sets aperture size of the graphics. The aperture is portion of the PCI memory address range
dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded
to the AGP without any translation.
¥ CPU Warning Temperature  
< Disabled >
This option lets you set the CPU temperature limit where the system will produce a warning indicating
CPU temperature has already exceeded.
¥ Current System1 Temp  (35 
°C/ 95 °F)
¥ Current System2 Temp  (0 
°C/ 32 °F)
¥ Current CPU Temperature  (50 
°C/112 °F)
These ready-only field reflect the function of the hardware thermal sensor that monitors the chio blocks
and system temperature to ensure the system is stable.
¥ Current FAN1 Speed  (6136 RPM)
¥ Current FAN2 Speed  (0 RPM)
¥ Current FAN3 Speed  (0 RPM)
These option and ready-only field show the current speeds in RPM (revolution per minute) for the CPU
fan and chassis fan as monitored by the hardware monitoring IS.
¥ VCore  (1.68 V) / VTTP  (1.48 V) / VCC   (3.32 V) / + 5 V  (5.18 V) / +12 V  (12.28 V)
These option and ready-only field show the current voltages in the voltage regulators and power supply

Block mode is also called block transfer, multiple commands, or multiple sector read/write. If your IDE
hard drive supports block mode (most new drives do ), select Enabled for automatic detection of the
optional number of block read/write per sector the drive can support.
¥ IDE Primary Master PIO

4-15. Watchdog Function
The QT-7300 features a system protective device, watchdog timer which can generate a CPU reset when the
system comes to a halt or failure. This function is to ensure the systems reliability during unattended operation.
The trigger sources for the watchdog contain both temperature over range and system failure. The system failure
may be caused by thunder, power glitch, radio interference, software bug or whatever reason.
To activate the watchdog timer, some program code similar to the following code has to be written to the system
running loops:
:
Loop: read (0x121) ; enable and trigger WDT
: ; interval time between triggers
if (END) GOTO END ; must be smaller than time-out
GOTO Loop ; period
END:
read (0x120) ; disable WDT
:
The time-out period ranges from 0.5 to 1000 seconds. If special settings for temperature or time-out are needed,
please refer to the utility diskette.
4-15-1. How to Use Watchdog Function
The user can read I/O Port 121H to enable Watchdog or disable it by reading I/O Port 120H.
Reset Watchdog - Read I/O Port 121H
Time_A - Read I/O Port 121H
Time_B - Read I/O Port 121H
Disable Watchdog - Read I/O Port 120H
** Time_B_Time_A < Time_Out    Setting **
In system Run_Time, you must still have to read I/O Port 121H to reset the Watchdog timer.
If the system fails, the TSR should be stopped and Watchdog reset action will be activated.
