In effect I suppose the improperly configured cache made the first 64K work incorrectly. This was also mentioned earlier the discussion - BIOS was never able to proceed far enough.
Interesting. I'm surprised it wouldn't give you the opportunity to enter CMOS setup before enabling the external cache. It does seem like these old Phoenix BIOSes are from the 8086/286 era and just barely had enough features added to work with a 486. The newer Phoenix BIOS (4.x) was acquired from Quadtel, I think.
