System: NetBSD 5.99.27 i386 as of Apr 13 2010
Architecture: i386
Machine: i386
	A recently built CD boot image when booted on this MSI
	motherboard with a P4 CPU exhibits the following symptoms:

	1) The kernel fails to find the booted-from device, and
	   therefore the root file system automatically

	2) The keyboard input (PS/2 interface) appears to be dead,
	   i.e. attempts at interacting with init to tell it the root
	   file system appears to be non-functional, even typing
	   "md0a" blind (nothing is echoed) gives no result.  The
	   keyboard *is* however able to break into DDB.

	Try to boot an i386 kernel from a CD image, watch it fail as

	Sorry, don't know.

 Oh, BTW,

 the boot block says:

 NetBSD/x86 cd9660 Primary Bootstrap

 >> NetBSD/x86 BIOS Boot, Revision 5.4 (from NetBSD 5.99.27)
 >> Memory: 630/1047488 k
 Press return to boot now, any other key for boot menu

 Now, it turns out the keyboard is not *completely* dead, it appears to
 detect about 1 in 50 keystrokes.  This lead me to try to point the
 install image in the direction of the preexisting root file system on
 the harddisk, only to discover that the kernel doesn't have the ffs
 module loaded at that time (only supports cd9660).  When I try to give
 it cd0a as root file system, it says "use one of md0[a-p] fxp0
 wd2[a-p] fd0[a-p] wd0[a-p] wd1[a-p] ddb halt reboot" -- it's as if
 it's not found the cd drive during autoconfig.  Grumble, I wonder if
 this is related to me using a separate plug-in card for the SATA disks
 I'm trying to do data recovery with. ... Which revealed another gripe:
 it appears that the boot disk has restore, but not dump on it, forcing
 me to make my own custom install CD *with* dump on it... =
