    UMAX VISTA SCAN

    A friend has an ASTRA 610S scanner on his WIN 98 computer with 64 MB ram memory. When he tries to use the COPIER utility, he gets an error message about STACK OVERFLOW. Any suggestions.

    Is it an old model? - I can't find it listed at the Umax site.

    This may help:

    Yup - tis old. I figure he got it with his computer which is a 166 MHZ no-name brand - figure about 5 years old. I will try the suggestions in MS knowledge base article and let you know. I had already checked the System.INI for minSPs or whatever they are supposed to be. No listing there at all. Thanks for your help.

    I think this may be related to the STACKS settings in your system files. You can't see this normally because in Win98 this and other settings that used to be controlled by Config.sys and Autoexec.bat are now managed by Io.sys. I believe the default is 9,256 i.e. 9 stacks each of 256 bytes, as in Win95.
    You can still insert a line in your Config.sys and this will override the Io.sys setting, eg:
    STACKS=9,256
    Try in this order: 9,512 and then if necessary 12,256. Any more than this and you may run into other problems as each stack uses a slice of precious base memory (the first 640K).
    As the system and scanner is old it may even be necessary to look at other legacy settings like FILES, BUFFERS and FCBS. Finally, IMHO the 64 MB RAM may be inadequate for a 166MHz CPU on Win98 while trying to use a scanner which tends to be a memory intensive task. Even though the motherboard is unlikely to be able to cache more than 64MB of RAM, adding some more will probably help matters, as will ensuring sufficient free space on the HDD for the Swapfile to handle the task.
    Sorry for the lengthy reply but that's just skimming the surface. Hope it helps.
