The top 40 bits of the LBA must be zero on CHS mode. Enforce this,

dns: don't get stuck on no packet received
Make sure the timeout actually gets processed. The right thing to do
for the receive loop is to check for timeout, then try to receive, and
loop until an acceptable packet has been received; we might as well do

core: Preserve IF through call16()
An intcall should always be invoked with interrupts off, but that is
not necessarily the case for a near or far call; in fact it is quite
the exception. As such, do not filter IF in our register image, and
for our own internal call16() interface, propagate the protected-mode
IF value into real mode, just as we do for the pm_call interface.
