Version 1.01 May 1999 4694 APM Riser Microcode Update and History RISER FIRMWARE HISTORY Version Filename Description ----------------------------------------------------------------------------- 27 STS_27.BIN Release level 28 STS_28.BIN Fix for problem where POS keyboard would wake the system up if AC was removed. 31 STS_31.BIN Add support for 205/245 DIRECTIONS This diskette includes the utility, binary file, and batch file required to update the firmware on a power management riser. First, make sure you have the power management riser card and battery installed. When you boot the system you will see a message: Battery Back Up Hardware Installed: Vxx (EC Level). To update your riser, boot on this diskette. STS.EXE is the utility used to update the riser code and ST_V31.BIN is the binary code file. V31 is the latest riser code. When the utility is complete press the space bar to reset the processor on the riser. The system will shut down. Use the power switch to turn the system back on. When re-booting verify the message has been updated to reflect the new EC level V31. Then, make sure the BIOS on your system supports APM. Here is the BIOS pre-requisite for each model that will be available with APM: MODEL BIOS -------------------------------- 104, 114, 124 7.07 or later 144, 154 5.14 or later 244, 254 9.11 or later 205, 245 C.08 or later APM BIOS support will add some menus to the SETUP screens. On the 104,114, 124, 144, and 154 you will see two new entries on the System Options page: APM Interface and External IRQMonitoring. The selections for APM interface are enable/disable, the default is enable. If you do not have an APM aware OS and application this should be set to disable. When disabled, there is no power management. The selections for External IRQ Monitoring are enable/disable, the default is disable. When this is enabled power management will montior external IRQs from the SIO bus (POS devices). This can be set to IRQ 7 or 11 on the ASIC Options menu. To use this feature you will need an APM aware OS, application, and POS drivers. With all three of these, the POS devices can be used to wake the system out of standby. When disabled the system will wake up only when a key is pressend on the PC keyboard or the power switch is pressed momentarily. Full APM support is available on the 244 and 254. You will see some more selections on the Advanced System Setup menu for these models. The four new entries you will see are: APM Interface, Power Savings Mode, IRQ for Standby Power, and External IRQ Monitoring. APM Interface selections are the same as those for the 104, 114, 124, 144, and 154. The selections for Power Savings Mode are suspend/standby. The default is suspend. In suspend the clock stops when the system is in power savings mode. When this is set to standby the clock slows down, functions like the 104, 114, 124, 144, and 154. The selections for IRQ for Standby Power are IRQ3/IRQ4. The default is IRQ 3. If you need IRQ 3 for a serial port, this can be reconfigured to IRQ 4. This selection is not available on the 104, 114, 124, 144, and 154 because that chipset hard wires the IRQ, it is not selectable. External IRQ Monitoring functions that same as described above. The only difference for the 244 and 254 is in addition to the PC keyboard and power switch, the PS/2 mouse will wake the system out of standby. The 205 and 245 models support APM and are ACPI enabled. There are no APM selections in the 2x5 Setup screens. APM is always enabled and these models only support SUSPEND mode. Some software drivers, such as Softex (used with NT) will still have a Standby option. Standby is not valid, the system will go into Standby briefly and then enter Suspend. When 4690 OS is installed on the 2x5 models the POS I/O can still be used to wake the system up. However, there is not an External IRQ Monitoring option. Instead, this is selected on the Wake-Up Event Sub-Menu of the Power Menu. IRQ 1 - 15 can be selected as events. If SIO is set to IRQ7, then IRQ7 must be set to Primary on this menu to allow the POS devices to wake the system up. The default is all IRQs disabled, except IRQ1 and IRQ12, which are the keyboard and mouse respectively.
