Message-ID: <6558@homxc.ATT.COM> Date: 6 May 89 19:08:43 GMT Organization: THE LABS Lines: 17 I am having trouble installing an 8087-2 Math Co-Processor in my AT&T PC-6300. I installed it in the only available like-sized socket on the motherboard and set Switch 5 to Off (0) on DIPSWITCH-0. But after doing so however, strange things happen. Depending on whether I have the switch set to "0" or "1", boot from the HD or a Floppy, I get error messages like "Replace Disk and strike any key to continue", i8087 Fails, or booting stops dead in its' tracks. When I remove the 8087, everything's fine. Should I be doing something else, like add a line to my CONFIG.SYS? I'd appreciate e-mailed (constructive) responses to this, my current dilemna. Thanks, Marv
