[comp.os.minix] 64K DMA wraparound bug

ast@cs.vu.nl (Andy Tanenbaum) (04/22/88)

A few weeks ago someone pointed out that if the kernel exceeds 64K, there
is a danger of some buffer crossing a 64K boundary and thus causing problems
with DMA.  I can't find the original message, but I am interested in fixing
this bug, if it is really there.  Will the author of the message or someone
else who has looked at this problem please contact me by email.  Thanks.
