486DX was 33Mhz. DX2 used some type of clock doubler to be 66Mhz internally
as I really.
I had a Cyrix drop in chip that was a DX4 effectively. That and 32 MB of
enough for Linux back then. I couldn't run X and compile RTEMS at the

No one has ever cared on the pc386 BSP. Every PC has more than
enough memory for RTEMS. We are talking easily less than 256K
for small applications. Exact number requires compiling yourself.
The variants are for specific cores.
And FWIW the proprietary disclaimer is utterly useless when you post to
list. You have effectively violated it yourself by sending to a mailing
list that is
publicly archived for eternity. And we will not delete it.
