note 1) The clock may not operate normallye, if the system is changed to the Suspend mode under the
Windows NT. The change setting under Windows NT is prohibited.
BIOS Timer is set at disable in Windows 98, and BIOS Timer Timeout does not activated.
Therefore, the Time set from the BIOS is invaid.
If the BIOS Suspend Timer timeout is activated, it changes its process depends on how the
APM BIOS is used in BIOS.
In Windows 98, the transition to the Suspend is available with OS Timer. Howeve, the
termination of this timer is not related to the Reload / Break Event setting from the BIOS
Setup. Reload / Break Event setting is required to resume.
If the APM BIOS is in use, BIOS send Suspend requests to the OS. It executes the Suspend
process from the BIOS in APM compliant OS (except Windows 98). Then it sends Suspend
command to BIOS, and BIOS executes the Suspend process.
If APM BIOS is not in use such as Windows NT and DOS, BIOS executes the Suspend
process.
