345a61fa7c Removed the redundant mem_write_null* functions (the few mappings that use them, now use NULL pointers instead) and made the _phys function used by DMA not write to the exec buffer if the address has no write mapping (as in that case, it's clearly not intended to be writable), fixes #1332. 2021-03-30 02:16:01 +02:00

d73011cd4c Early implementation of the Intel 450KX 
450GX & 450KX are the first chipsets intended for the i686 era of processors. Mostly they were used on workstations and servers but also a few general boards. This is an early implementation, not complete due to 86Box limitations in terms of memory handling.
