I have an ATT 6300 PC. I have trouble keeping the clock set. It gradually looses time, a few minutes every day with occasional jumps. I beleive the battery is getting weak. Can anyone tell me where the battery is installed, what it looks like, how I replace it, and where I can get a replacement battery for a reasonable price? Thanks John Zavgren

Before you replace the battery, check to see if you are running AT&T DOS 3.2. There is a bug in the system that resets the seconds to zero everytime you re-boot the machine. This causes the clock to gradually lose time. There is a patch to AT&T DOS 3.2 to fix the clock problem. If you need it drop me a line. -- Bob Jackson (rdj@ttrdf) 312-982-3578 AT&T Data Systems Group 5555 Touhy Ave., Room 178-6, Skokie, IL 60077 PATH: ...!ihnp4!ttrdf!rdj

The Doctor (in Robots of Death) If you're running AT&T's MS-DOS version 3.2 it's possibly a software bug! They read the clock on boot and write back to it -- often losing as much as 59 seconds per boot. I was losing a few minutes per week because of reboting during software development. I recommend a file called biopatch16.arc available from the Right Choice BBS in NJ (201) 974-8317 and possibly from AT&T's support bbs (201)769-5616. The program patches the boot code in the bios to eliminate this bug -- which HAS BEEN reported to AT&T (and they are doing NOTHING about it. (Their hardware techs didn't know and were going to swap my motherboard to fix the problem -- they were getting deluged with motherboard swaps after v3.2 hit the 6300's (and 6300+'s). -- Bill Pechter {sun!hoptoad,cmcl2!phri}!dasys1!pechter USnail 103 Governors Road, Lakewood, NJ 08701 AT&T 201-370-0709 Evenings
