I've seen an ad* for a device to fix the "errata 21" problem with the 80386 processor running with a '387 and DMA in protected mode. I dimly remember hearing about a design bug admitted by Intel that sounds like this. We're evaluating a 386 system and the technical representative says they don't have this problem. They use "step DX" 386s and Chips & Technology VLSI support chips. My questions: Is this a problem to be concerned about? Is it fixed in the "step DX" 386s? Is there some offical Intel notice of the problem that I can use to get some real answers/action from my vendor? Please reply by mail. I'll summarize what I get. Thanks for any help! *Infoworld Jan 30, 1989 p. 62
