[comp.arch] i860 instruction cache

Hi!  I have a dumb question about booting up an i860.  In the hardware
reference manual, under section 8.9.2 Certain Gotchas when Debugging with i860
Microprocessor, it says "After reset, the instruction and data cache may
contain data so the cache flush procedure should be used to reset the
instruction and data cache."  How do I get the boot code into cache in the
first place?  Is there a possibility that the cache contains random data and
"thinks" that the boot location (0xffffff00) is cached and refuses to read the
real boot code?
