This option 115111314Snyan# is useful when you use Socket 8 to Socket 370 converter, because most Pentium 116111314Snyan# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs. 117111314Snyan# 118111314Snyan# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1). 119111314Snyan# 120111314Snyan# CPU_SUSP_HLT enables suspend on HALT.

This option is only needed if I586_CPU is also defined, 138111314Snyan# and should be included for any non-Pentium CPU that defines it. 139111314Snyan# 140111314Snyan# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors 141111314Snyan# which indicates that the 15-16MB range is *definitely* not being 142111314Snyan# occupied by an ISA memory hole. 143111314Snyan# 144111314Snyan# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32 145111314Snyan# machines.
