VIPer Software Setup 9-11
TABLE 9-2:
Chipset Setup
Option
Fail-safe Defaults
Optimal Defaults
Possible Settings
Description
DRAM Wait State
2 wait
1 wait
1 wait, 2 wait
This option allows the selection of a wait state for DRAM reads and writes.
SYSCLK Divisor Select
Auto
Auto
Auto,
CLOCK2IN/2, CLOCK2IN/3,
CLOCK2IN/4, CLOCK2IN/5,
CLOCK2IN/6, CLOCK2IN/8
Sets the speed of the ISA bus clock (SYSCLK) signal, which must be set to approximately 8MHz. The appropriate divisor depends on
the CPU external bus speed.
AT Ready Delay Selects
2HS1XCLK
No Delay
No Delay, 1HS1XCLK, 2HS1XCLK
Sets the number of SYSCLK wait states to add, after a ready is received on the AT bus.
Back to Back I/O Delay
3 SYSCLK
0 SYSCLK
0 SYSCLK, 1 SYSCLK,
2 SYSCLK, 3 SYSCLK
Sets the delay, in terms of ISA bus clock, between consecutive ISA bus I/O cycles. This option is used for older ISA devices which
require longer delays between consecutive I/O cycles. Due to the higher speed of new processors, it may be necessary to add the Back
to Back I/O Delay for these older adaptor card.
ISA Refresh
Enabled
Disabled
Enabled, Disabled
This option enables the refresh cycle on the ISA bus. Some ISA peripheral boards use the ISA Refresh signal (for example, bus
mouse).
Turbo IDE Function
Disabled
Enabled
Enabled, Disabled
This option enables the Local Bus IDE.
Turbo IDE Command Width
9HS1XCLK
9HS1XCLK
2HS1XCLK, 3HS1XCLK,
4HS1XCLK, 5HS1XCLK,
6HS1XCLK, 7HS1XCLK
8HS1XCLK, 9HS1XCLK
Sets the pulse width of read and write accesses from and to the hard drisk. HS1XCLK is the same speed as the CPU bus clock. The
minimum required pulse width varies from drive to drive. Consult your hard disk specifications for minimum pulse width.
Turbo IDE Back to Back Delay
16HS1XCL
16HS1XCL
2HS1XCLK, 4HS1XCLK,
6HS1XCLK, 8HS1XCLK,
10HS1XCLK, 12HS1XCLK
14HS1XCLK, 16HS1XCLK
Sets the delay between hard disk accesses. HS1XCLK is the same speed as the bus clock. The minimum required delay varies from
drive to drive.Consult your hard disk specifications for minimum delay.
TABLE 9-3:
Power Management Setup
Option
Fail-safe Defaults
Optimal Defaults
Possible Settings
Description
Power Management /APM
Disabled
Disabled
Enabled, Disabled
When Enabled, activates power saving modes: DOZE, SLEEP and SUSPEND.
DOZE Mode Time Out
Disabled
4 sec.
Disabled,
1, 4, 8. and 16 sec.
This option sets the time-out period to enter into Doze Mode when inactivity is detected.
SLEEP Mode Time Out
Disabled
1 min.
Disabled, 1, 2, 4, 6,
8, 12, and 16 min.
This option sets the time-out period to enter into Sleep Mode from Doze Mode.
Hard Disk Time Out
Disabled
Disabled
Disabled, 1, 2, 3, 4, 5, 6, 7 min.
This option enables a non-activity timeout, after which the hard disk is put into Standby mode. Note that once the hard disk has
entered Standby mode, the next hard disk access will take a few extra seconds to occur.
Video Standby Time Out
Disabled
Disabled
Disabled, 5, 10, 15
30, 45, 60, 90 sec.
This option enables a non-activity timeout, after which a video display is put into Standby mode. Any subsequent detected activity will
reenable the display.
SUSPEND Time Out
Disabled
5 min.
Disabled, 5, 10, 15
20, 30, 40 and 60 min.
This option sets the time-out period to enter into Suspend Mode from Sleep Mode.
Resume with Modem Ring
Disabled
Disabled
Disabled, 1, 2 and 4 Rings
Enables and specifies the number of modem rings required to re-activate the CPU when in Suspend Mode
Suspend Warning Beeps
Enabled
Enabled
Enabled, Disabled
When Enabled, warning beeps will be sounded before entering Suspend Mode.
