I have recently fitted and ATAPI Zip drive to my old PC running NetBSD 
3.0. It is detected and configured OK and I can mount partition h:

However, reading anything other than very small files I get a kernel 
error 'missed interrupt'. Looking though the archives it seems people 
have had this problem since v 1.6 but I could find no reference to a 
solution. Some suspicion was ploaced on VIA chipsets but my PC has an 
Acer chipset. Is there a definitive solution to this (BTW I have 
installed the 3.0.1 kernel and this made no difference)?

Cheers

Ian
