We have been told that up to (?) 25MHz version, the 386 processor had to have the sigma-sigma sign on it to be able to run Unix (for DOS it had to be sigma-pi). Is it still true for the 33MHZ version? (we have the processor without any such sign). 2. We have been told that "D" version of the processor is error-free. Does the DX mean that we have D-version (we have a processor with the following set of inscriptions: i386 A80386DX-33 IV SX219 L0291855 INTEL (m) (C) '85 3. Where can we find the program testing the multiplication error (which has been announced in '87)? These are all specific questions I have been asked to post. Maybe you have some other comments about Unix running on such processor? I would greatly appreciate e-mail answers to me (jam@ida.liu.se), possibly with a Cc: to marekk@amargosa.uucp, the original source of question. But I'll try to read these groups for some time. TIME is important, as they have possibility to exchange the processor or the whole motherboard up till the end of January.
