System: NetBSD azarin 1.4P NetBSD 1.4P (AZARIN) #84: Wed Dec 1 21:54:14 JST 1999 kei@azarin:/a/anoncvs/netbsd/src/sys/arch/macppc/compile/AZARIN macppc


>Description:
	Due to the problem of detecting endianness, cdrecord didn't recognize
	my MATSUSHITA CW-7502 on my macppc machine.
>How-To-Repeat:
	connect CD-R to a powerpc box and see cdrecord fails to work.
>Fix:
	replace patch-ac to this (patch to the patch file is hard to read, so
	I send new version).

	XXX with this patch, my macppc box properly probe my CD-R drive, but
	on-board mesh is instable with DMA bulk transfer and causes SCSI bus
	lock up.  It's only SCSI hardware on my macppc box, so please someone
	who has another on-board SCSI or cards test and commit this?

	My sparc classic works well with this drive for 4x speed writing with
	this patch.

	XXX I didn't test this with little endian machine.
