that have multi-purpose rooms which can be reserved ahead of time. The big drawback to thi option is parking availablity. So this option shoul really be considered on a temporary basis only.

LA Fox provides a valuable service to its membership. The first meeting I attended featured Adam Greene, at the time one of the best-known xBase developers in the country. Here was a man that thousands of people have paid hundreds and thousands of dollars to see, listen and learn from. And I was seeing him for a mere $5.00 visitor’s admission. Since then, our meetings have featured the likes of Dick Bard, Nancy Jacobsen, Lisa Slater, Mike Feitman, John Miller, Ken Levy, Les Pinter, and many others involved in the advancement of FoxPro programming techniques. In our newsletter, we try to provide the most up-to-date information about the FoxPro community, programming tips, hands-on product reviews, and other items of interest. And among our ranks are several published authors. I believe that anyone in the group would be hard-pressed to find a better value for their dollar.

All of this has been accomplished by the board with little involvement from the membership. And it’s all been relatively hassle-free. And perhaps that’s part of the problem. But now it’s time for the entire membership to get involved. We need to find a new place to meet, even on a temporary basis untill we can locate a permanent one.

We’re not locked into the third Tuesday of every month (some of us might have to break old habits), we not locked into specifically 7:30 (some of us might have to reset our alarm clocks), and we’re not locked into a specific location (some of us might have to drive a little farther).

So help us out. You can reach us by calling Chuck
Williams at (310) 539-9439 I CID# 72330,2326 or
Barry Lee at (714) 968-4225 / CID# 72723,3422.

Traversing the GP Fault (Con't from page 3)

Modify the “advanced chipset features” in the
CMOS/BIOS. Sometimes there can be conflicts in the
CMOS setup. To modify these features, follow these
steps:

1.
Press the escape sequence keys, during system
startup, to access the CMOS setup. On some computers, this can be done by pressing the “delete” key during system startup. Before proceeding, do a “print screen” to the printer so you have a hard copy of the original setup in case you need to recover it.
2.
Proceed to the “advanced chipset features”
section.
3.
Disable (normally with the Page Up/Page Down
keys) CPU Internal Cache, External Cache, System BIOS Shadow, Video BIOS Shadow, and flip the Gate A20 Option to “normal” (HIMEM.SYS has been designed to use several different A20 handlers). Save the settings and exit the setup.
4.
Next, re-boot the machine and start Windows.
You’ll notice that everything has slowed down substantially. Unfortunately, you’ll have to run like this until you can determine that any of these settings are not causing the GPF. In other words, if you’re still getting GPFs, the original CMOS settings may not be the cause. If you’re no longer getting GPFs, then one of these features is causing the fault.
5.
Once that determination is made, turn these
features back on, one at a time , in this order: CPU Cache, System BIOS Shadow, External Cache, Video Cache, and flip the Gate A20 Option back to its original position. As you turn these features back on, save and exit from the setup, and reload Windows.

Make sure there are no incompatibilities in your system. These incompatibilities may be in anything from software memory address conflicts down to the board component level. Some examples that immediately come to mind are:

1.
If GPFs occur in 386 enhanced mode, but do not
occur in standard mode, your system may have a memory conflict in the upper memory blocks (UMBs). To eliminate the possibility of a UMB conflict, insert the following line in the [386Enh] section of the SYSTEM.INI file:
EMMExclude=A000-EFFF
