Blue screen error

A VxD is a virtual device driver. Simply put, it's a piece of software that provides the interface between a hardware device and the operating system. Stack space is a special portion of memory for storing items of temporary interest - kind of an electronic scratchpad, as it were.

In a default SYSTEM.INI, there is no definition for MinSP so it's not surprising you didn't find it when you opened SYSTEM.INI in Notepad.

Microsoft's recommendation is to add a line in SYSTEM.INI under the [386Enh] heading like this:

MinSPs=8

Start with 8 and increment by 4 (e.g. 8, 12, 16, 20) until the error goes away.

This information can be found on Microsoft's TechNet site in article Q149083 (www.microsoft.com/technet)

Hi
OS=WIN9X
The problem is:
Your Windows has an internal overflow of the stacks that are used by VxD.
Cuase could be:
stack overflow occurs when any device driver has errors caused by not enough allocation of pages for a device driver
set by "MinSPs" setting or device driver problem itself (damage file(virus),bad programing (using stack space), compatbility with os or limitation "16 bit device driver should set compatbility in win.ini file" to access stack space)
Solution:
1-Set the "MinSPs" setting to allow enogh space stack pages.These pages are reclaimed by windows later when no need for them after booting.(when no stack overflow happend).
2-Check your device driver is the correct one and not damge (maybe by a virus).
setcomppatbility in win.ini file if needed.
Defintions:
I- VxD is a 32-bit Windows based (Virtual ) device driver .(Special type of program which gives the cabapility of dealing with that specific device by a specific operating system)
II- MinSPs is a variable sets minimum spare stack pages under [386Enh] section in system.ini startup file to protect system from stack overflow.
To set "MinSPs"
1- edit the System.ini file by notepad (as you didi before).
2-find [386Enh] section then locate the line MinSPs=X
(if the line is not there {default} add it) and set it to say MinSPs=8 (if you still have the problem increase it by 4 till no problem).
3-save the changes
5-Reboot your machine.

III- Stacks space is the memory which is reserved for stack pages.
You can check more in these stack problem in technet (spcially programming) and if the driver is just installed andthe problem just happend with the vendor of the device to get you the lates device driver.I hope this help you.
