Date: Thu, 04 Feb 93 09:19:34 -0600 From: Mark Littlefield Sorry to bring this up again but we've been having mail problems here and apparently I was accidentally dropped from the list for a time so I didn't see any responses from my last query. What I need to do is access certain memory locations in the 0xE0000000 memory range (>256 meg). These locations are mapped to the VME bus that our 486 is attached to. I've look at the docs and the sources and I don't see an obvious way of addressing physical memory in protected mode (all of the memory gets mapped one way or another). If there was any discussion on this topic after my last query I would appreciate it if some kind soul would forward the responses to me. thanks, mark ===================================================================== Mark L.
