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.
