309# The npx registers are normally used to optimize copying and zeroing when
310# all of the following conditions are satisfied:
311# I586_CPU is an option
312# the cpu is an i586 (perhaps not a Pentium)
313# the probe for npx0 succeeds
314# INT 16 exception handling works.
315# Then copying and zeroing using the npx registers is normally 30-100% faster.
316# The flags can be used to control cases where it doesn't work or is slower.
317# Setting them at boot time using userconfig works right (the optimizations
318# are not used until later in the bootstrap when npx0 is attached).
319# Flag 0x08 automatically disables the i586 optimized routines.
