Thus recover ; R14 ;R30 03/04/99 JDN Added Use_CPU_IDLE_In_APM12 define for APM1.2 ; In APM1.2 Timer is disable ,so CPU Idle can't work ;R29 02/23/99 RCH Added AMD/K7 CPU support. ;R28 02/08/99 ATN Disable APM when PM_option_item is disabled by user ; to prevent problem generated by SCO/UNIX. This is ; an option feature. ; ;R27 01/27/99 RAY HCT8.x HDD time out failure if tester test the ; whole HCT APM test. ; ; It is found that the HCTs (7.x & 8.0) do not call ; function 0Dh to disable the HDD timer before waiting ; a 5 minute period to see whether HDD will time out ; or not. Thus it rely on the OS(Win98) to disable ; the HDD timer. ; ; For HCT 8.x, after one of the test before the ; Device Power Management test, it issues a call ; to function 08h to enable system power managament. ; We also enable the HDD timer in 08h and thus cause ; the symtom. ; ; Patch: do not touch the HDD timer in Function 08 ; ;R26 09/29/98 RAY Moved the "Set_HDD_Standby_Timer" from PMKERNAL.ASM ; to APM.ASM. Inside function 08h & function 0Dh , ; invode this routine to disable/enable HDD timer. ; ; Reason: ; ------- ; New HCT Test required the BIOS to disable HDD ; time-out if the following functions are being ; called: ; ; - "PM Disabled"(Function 08) ; - "Secondary storage PM Disabled (Function 0Dh) ; ;R24B 08/13/98 TNY Fix coding error.(Win95 APM1.2 fail if "APM_IN_SMBASE" ; defined) ;R25 07/03/98 TNY Add "SET_APM_FUNC05_HALT" option. ;R24A 06/26/98 RAX Support device power management for Function 0Dh & 0Fh ;R24 06/17/98 RAY Support device power management for Function 0Dh & 0Fh ;R20A 03/26/98 RAX Fixed mistake. ;R23 03/25/98 RAX Change compiler to MASM6.X. ;R22 03/04/98 RCH Fixed system sometimes hang up while compiling this ; file ;R21 02/03/98 RAY To let Win95 Shutdown-->PowerOff functionality ; still exist if PM is disabled in CMOS Setup. ;R20 12/19/97 RAX Add define for move APM code to SMBASE. ;R19 11/24/97 JKY Power source change no issue SMI , HCT APM test ; for change normal notify will fail , please define ; 'POWER_CHANGE_PASSIVE'. ;R18 10/27/97 KGN move defin LCD_CRT_OPTION to common.equ ;R17 05/06/97 DNL Added ACPI function support ;R16 04/30/97 KVN Merge APM and APM32 into APM.ASM ;R15 04/25/97 DNL Add batery function for APM 1.2 ;R14 12/06/96 RAY Problem: ; ; Fail to install APM under SCO-UNIX. ; ; Fixed: ; ; In function 03h, the output SI which according to ; the specification describes the 32bit code segment ; size. We found that under a SCO-UNIX environment, ; we must not destroy the input SI in order for the ; system to install APM successfully. Furthermore, ; this workaround will not affect the test result ; of the WIN95 SCT test ; ;R13 10/11/96 DNL Added LCD only model support ;R12 09/20/96 DNL Added APM1.2 function support ;R11 09/11/96 RCH Don't report PCMCIA capabilty due to WIN95 SCT v5.10 ; don't like it for desktop system ;R10 09/06/96 DNL Added codes for Notebook Power Management. ;R09 09/06/96 DNL Return correct SI to solve windows95 SCT test fail ;R08A 09/05/96 DNL Rewrite code to solve windows95 SCT test fail ;R08 08/15/96 DWR Remove Need_Chk_All_Devices from APM_FUNC0A ;R07 07/16/96 RAY Do not issue any SW SMI in Function 08h if NO_SUPPORT_APM12 ; is defined even though this is not a new feature of ; APM v1.2 ;R06 07/03/96 RAY We should also return the remaining battery life ; (percentage of time unit) as UNKNOWN or 0FFFFh, i.e. ; DX=0FFFFh in desktop system. ;R05 06/05/96 RAY Save codes ;R04 06/04/96 RAX Add define for make Non PM_SUPPORT bios ;R03A 05/30/96 RAY R03A will destroy the parameters of Function 11h ;R03 05/29/96 DNL Fixed bug of system halt while the POWER.EXE installed ;R00A 05/29/96 DNL Fixed coding mistake ;R02 05/28/96 RCH Move "APM_INIT" to MISC.ASM due to not run-time code ;R01 05/24/96 RAY Reason: run time code overflow starting from F8000 ; when CD_ROM & DMI stuff is added ; ; Solution: ; ; Move CRT control related routines to a include file: ; CRT_CTRL.INC.
