According to my PC164 manual, 6 beeps is the same as POST code 3F
fatal error subcode 6, which is:
	Checksum error detected when image was read back from memory

Sounds like dodgy memory to me.

Also, have a search around www.netbsd.org and any links off into the
old Digital/DEC pages at Compaq; I think that there might be a pdf or
postscript copy of the PC164 manual available there.
