If a process switches to virtual x86 mode, wouldn't virtual memory page for address 0 (which includes the software interrupt table) get mapped to a per-process page in physical memory? Would that have anything to do with the RAM at physical address 0x64? > What problem is the memory defect actually causing that is troublesome ... The OP stated, "Every few weeks some Linux program would go wacky. Each time is was a different program and a different wackiness. (There were not enough wacky observations to conclude that the same effect in the same program never ever repeated.) Reboot restored proper operation." He hasn't mentioned anything that really proves the wackiness is due to the bad RAM, although I think that's a reasonable assumption to make at this point. My fear would actually be that the bad cell at physical address 0x64 is just the tip of the iceburg, and that other cells are developing issues over the week-long periods he mentions. -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
