WordPerfect 5.1 On An Old IBM PC Computer |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: A customer using a true IBM PC (very old model) cannot get into WP51, the computer locks. They receive the error "Divide Overflow". They do not have a AUTOEXEC.BAT and the CONFIG.SYS has only "files=20" in it. The options FIXBIOS, and WP/X/NC/NK/MONO/NE were tried with no success the computer just locked on "Please Wait". On another similar IBM PC in the same environment the computer gives machine language on the screen. The same disks were used on a new NEC PowerMate 386-25 and they worked with no problems. Is it possible that older IBM PC's are not compatible with WP51? Solutions: We tested on 2 different "Old IBM PCs" at 3rd Party that had 64k with expansion cards, both had no problem running 5.1. There was another customer that had the same problem using this same configuration. He corrected the problem by switching some chips in the computer. The 256k chip needed to be set at address 256k, rather than adjacent to the 64k on the mother board. Increasing the Buffers corrected this problem on one of the machines. Another user with a NEC Powermate portable computer corrected the problem by starting WP with /MONO. |
