Symptoms:
	PHKL_19786:
	DTS# JAGab72357 SR# 8606104808
	This patch provides new functionality to support
	HP VISUALIZE-fxe graphics.

	DTS# JAGab11382
	dd of a CD using raw device and 8K blocks ends in error

	DTS# JAGab12903
	mount command hangs on Toshiba CDROM drives

	DTS# JAGab72943 SR# 8606105091
	Reading more than 64KB in one read command hangs CDROM

	DTS# JAGab72940 SR# 8606105090
	Mitsumi CDROM drive causes kernel panic on bootup

	PHKL_17638:
	This patch enables new functionality that is part of the
	10.20 AC (Additional Core Enhancements) Workstation bundle,
	and J5000 systems.

Defect Description:
	PHKL_19786:
	DTS# JAGab72357 SR# 8606104808
	New funtionality to support HP VISUALIZE-fxe graphics
	Resolution:
	Added the new functionality.

	DTS# JAGab11382
	dd of a CD using raw device and 8K blocks ends in error
	Resolution:
	Fixed the way residual data is calcualted at the end
	of s read.

	DTS# JAGab12903
	mount command hangs on Toshiba CDROM drives
	Resolution:
	Added handling for a check condition on an Inquiry
	command which is returned by Toshiba upon a media
	change. This is an unusual case since Inquiry
	command does not normally return check condition
	on media change.

	DTS# JAGab72943 SR# 8606105091
	Reading more than 64KB in one read command hangs CDROM
	Resolution:
	This was caused by a limitation in the IDE DMA
	controller which can not transfer more than 64K in
	a single transfer. Added code to break single large
	DMA into multiple smaller ones.

	DTS# JAGab72940 SR# 8606105090
	Mitsumi CDROM drive causes kernel panic on bootup
	Resolution:
	Mitsumi drive breaks the IDE norm of setting the
	cylinder register to the number of bytes CPU should
	read for the Inquiry command. There was an arbitrary
	large number left in the cylinder register which
	caused CPU to rea too much data and cause an overflow.
	Added code to deal with this oddity.

	PHKL_17638:
	New functionality to support the B1000, C3000, and J5000
	systems on HP-UX 10.20
	Resolution:
	Add new functionality for IDE/ATAPI CDROM
