	FreeBSD 5.0-DP1/floppies

>Description:

	(1)
	After two floppies loaded, neither "boot -c" nor the normal boot
	will stop for interactive configuration.
	The error message says that

		ACPI no autoload failed -- no such file or directory

	(2)
		ata is still forced to configure even though the BIOS
	has disabled IDE controllers.
		It is important to allow to disable IDE (ata0/1) to
	free more IRQ when SCSI disk is used, because current the PC
	motherboard has limited IRQs.

		If 5.0 will disbale interactive configuration mode,
	this becomes more important to read BIOS configuration info
	for auto-configuration.

>How-To-Repeat:

	Try 5.0-DP1 installation floppies.

>Fix:

Sorry for the very long time it has taken someone to look at this bug 
report.  Could you confirm whether this problem occurs with a recent 
FreeBSD releases, such as 6.3-RELEASE or 7.0-RC1?  Otherwise we'll 
close it as 5.0 is an increasingly long time ago.  Thanks!

 ata1 still cannot be disabled in 6.3-Release. Not tested in 7.0-RC1 yet.
 
 It does not matter if adding hint.ata.1.disabled=1 in /boot/device.hints 
 or setting this variable at boot time, ata1 will still configured.
 
 Is possible completely disable ata device? If so, then we can close this
 case.  If not, then I will provide a suggestion.  The reason to disable ATA
 is becasue if I use only SCSI or USB, there is not need to have ATA module
 in kernel to take memory space,

 Hi, Jin.
 
 ata(4) drivers doesn't use device hints mechanism. So
 you can't disable it via hints. If you don't want to use
 it then remove ata(4) from your kernel and driver will not
 use any resources.
