I didn’t think Linux ran on an SX. Thought it required the mmu in the DX for 32-bit protected mode. Might be misremembering though.

- icedchai 5y agoYes, you were misremembering. The 386SX had an MMU. However it had 32-bit internals, like the DX, but 24-bit address space (16 meg limit) and 16-bit memory access.
- Teknoman117 5y agoThere was only one variant of the 386 that did away with much of the MMU functionality - the 80376. It was largely overshadowed by the 386EX. https://en.wikipedia.org/wiki/Intel_80376 https://en.wikipedia.org/wiki/Intel_80376
