Hi Jim, Interestingly, there is a NVIDIA edition of the M6117. https://theretroweb.com/chipsets/182 https://theretroweb.com/chipset/documentation/m6117d-6272973f0727d519812742.pdf
3.1 Static 386SX Core The 386SX core is the same as M1386SX of Acer Labs. Inc. and 100% object code compatible with the Intel 386SX microprocessor. System manufacturers can provide 386 CPU based systems optimized for both cost and size. Instruction pipelining and high bus bandwidth ensure short average instruction execution times and high system throughput. Furthermore, it can keep the state internally from charge leakage while external clock to the core is stopped without storing the data in registers. The power consumption here is almost zero when clock stops. The internal structure of this core is 32-bit data and address bus with very low supply current, 116 mA in the conditions of 5.0V, 20MHz, room temperature. Real mode as well as Protected mode are available and can run MS-DOS, MS-Windows, OS/2 and UNIX
100% seems a bit optimistic ;-) There also are some custom SMI related opcodes, see chapter 4.5, and the M6117 seems to be a relative of the Vortex86 SoC. But to get back to the original topic, DOSLFN should not use SALC, if it wants to be compatible to Pocket 386 PC.
