PCs that won't run Family Search
- *************** Rick P asked me to forward this message to the list
I have posted several items on here about PCs that will not run Family
Search. This is an update
A number of modern PCs will not run Family Search under any operating system
failing with an error indicating no EMS memory. It is particularly prevalent
when running under ME, 2000 or XP. I originally thought this was due to the
motherboard manufacturers no longer supporting the LIM interrupts but this
may not be the case.
The recommendation is to load EMM386 by a line in Config.sys such as
Device=EMM386.EXE 1024 RAM
This fails with a message "Cannot create a Base Page Frame Address" This
occurs because a minimum of 64kB or RAM must be available in the Upper
Memory Area and typically it is not. Windows ME, 2000 and XP do not support
real mode drivers and make no use of Config.sys. In these OS's the
recommendation is to include a line
In Config.NT and to set the EMS memory to 1024 in the PIF for PAS.EXE. This
also fails with a similar message if you are lucky
Running a DOS program under Windows utilizes a 16bit Virtual Machine (VDM)
and the problem can best be explained by calling the Command Prompt from
Then run MEM /C
This will list the programs which run in the bottom 640KB memory and the
Upper Memory Area between 640KB and 1MB
And in the upper memory area
The computer will attempt to load as many of these into the UMA as it has
space for and is permitted to.
If this process leaves 64KB left in UMA then EMM386 will load with the RAM
switch. If not then EMM may still load without the RAM switch ie delete the
EMM=RAM line. If it also leaves 593KB free in the main memory below 640KB
then FamilySearch will load. However I have four machines with SYSTEM taking
up 196K, 208K, 234k and 243k respectively/ The first will run, the last
three will not. As System grows there is no longer space to load DOSX in the
UMA and it is placed in the conventional memory. Then Family Search will not
If anybody knows how to influence the size of SYSTEM it could help us all.
The machines are not significantly different and they have defalt
installations of the OS
Note: you may have to look at command prompt BEFORE you attempt to load
Family Search since the display differs once it has been loaded.
At the moment my rule of thumb is that if DOSX will not load high then FS
will not run - so don't buy the PC!

Salt Lake... can you give us an idea when Family Search will be released
in a Windows version?
