Disk Cache Errors With Expanded Memory QEMM38
DocumentID: 654367
Revision Date: 29-Feb-96 8:29:30 PM

The information in this document applies to:
WordPerfect® 5.1 for DOS

Problem

Symptoms: A customer using expanded memory (QEMM386.SYS) v 6.0 is unable to enter WordPerfect because he receives disk caching errors. Solutions: The customer is using a Cache program. According to the READ.ME file sent by Quarter Deck for version 6.0 the option DBF is "Useful when using programs that write directly into the page frame using the BIOS-level calls, such as some EMS-using Disk caches (including PC-CACHE, Norton N-CACHE, and the Compaq cache). In most cases it is preferable to reconfigure the cache so that is uses extended memory. The value specified by 'XX' (representing number of kilobytes of RAM to be used for buffering) can be anything, but useful values might be 2 and 10. The memory used by DISKBUFFRAME comes from conventional memory. When DISKBUFFRAME is active, EMM386 will only buffer INT 13's (disk reads and writes) that directly access the EMS page frame. Qemm-386 should prompt you with an on-screen message if you are using a program that requires the DBF parameter."

I would like to give a word of caution. We would better serve the customer by having the customer contact the manufacture. We get into trouble when trying to assist the customer with problems related to the manufacture's software. Quarter Deck problems should be directed to Quarter Deck. Please refer to Folio POL_108.
