readers.
A final point is that the process of loading both the palette RAM and
DAC registers involves performing multiple **OUT**s to the same
DAC registers involves performing multiple `OUT`s to the same
register. Many people whose opinions I respect recommend delaying
between I/O accesses to the same port by performing a **JMP \$+2**
between I/O accesses to the same port by performing a `JMP \$+2`
(jumping flushes the prefetch queue and forces a memory access—or at
least a cache access—to fetch the next instruction byte). In fact, some

people recommend two `JMP \$+2` instructions between I/O accesses to
the same port, and *three* jumps between I/O accesses to the same port
that go in opposite directions (**OUT** followed by **IN** or **IN**
followed by **OUT**). This is clearly necessary when accessing some
that go in opposite directions (`OUT` followed by `IN` or `IN`
followed by `OUT`). This is clearly necessary when accessing some
motherboard chips, but I don't know how applicable it is when accessing
VGAs, so make of it what you will. Input from knowledgeable readers is
eagerly solicited.
