GamePort VXD:
	Formal release version 1 working on Windows 98
	a. reguest game port length from 2 expands to 8 to avoid unreported IO access for HCT test

Audio WDM - als300p.sys

	Special version for CLEVO to help them get the WinKey logo
	1.	fix the bOemProduct as OEM_CLEVO_NOTEBOOK
	2.	GPIO0~2 as the GPIO for Volume up/down control
	1.	GPIO0 as the GPIO for Plug-in detection
	2.	support plug-in detection for CLEVO
	3.	add virtual volume control for every recording channel
	4.	fix power down resume hang problem when IRQ is shared (avoid IO access in ISR when power state is D3)
	5.	avoid power down fail and hang problem when pcm is playing (avoid DS-GetPosition)
	6.	fix HCT disabler fail (mixer:GetDescription connection number counting error)
	7.	check parameter passing to WAVEIN_MUX control and return INVALID_PARAMETER back to portcls to avoid HCT GP fault
	8.	if OEM_CLEVO_NOTEBOOK, disable Video&Aux mixer control

	1.	Special handle for E version -
		Do not Cold Reset.
		Before initializing, Set GPIO7 as output then output GPIO7 1->0->1->0.
		Finally, restore GPIO7 as input.
	1.	CreateMiniportMidiFM by ourself which modified from MS FmSynth library source code.
		Modify the handle procedure of KSSTATE_PAUSE to pass the ACPI compliance test of OPL3.
