I'm experiancing several errors in a true-blue PC when it is powered on. Specifically, I'm getting a 1550 201 error on power up. Could someone tell me where I can get a reference that will diagnose what this is? [my guess is a memory error with 1550 being some kind of address. if this is so, how can i figure out what chip it is?] ...bruce Bruce Martin Jr. UC Davis Dept. of Computer Science martin@iris.ucdavis.edu -or- ...!ucbvax!ucdavis!iris!martin

It is indeed a memory error and 1550 is the location of the error. Recently a friend of mine experienced this same problem and when I solicited this newsgroup for help in determining the problem chip I got about seven different locations mentioned to me. Looking at my IBM Hardware Technical Reference Manual, at the memory map diagram for the system board, the error you have experience is in bank 1. The book says it occurred between the 80K to 96K range but I realize that is not very helpful. (This is relative to bank 0). Finally, you should know that after all the suggestions came in my friend tried swapping chips with some good chips according the what everyone had recommended. Nothing worked and she finally took it into Fry's Electronics in Sunnyvale. A day later she got a working machine back. By the way, I should mention that 1550 is hex, not decimal. danielle (I haven't been any help) bercel -- UUCP: {hplabs,decvax,}!sun!toto!{danielle,dbercel} /-------------------------------------\ | Toto, I don't think this is Kansas. | -- Danielle Bercel \-------------------------------------/ Sun Microsystems, Inc.
