MS-DOS Compatibility Mode
My system is running its virtual memory by using MS-DOS compatibility mode. How can I change it to use 32-bit access? How can I determine which drivers are using MS-DOS compatibility?
Ekrisch: I presume you mean that windows 95 is accessing your hard drive via ms-dos compatibility mode. If this is the case, the following are the normal reasons for that occurring.
- An "unsafe" device driver, memory-resident program, or virus
hooked the INT21h or INT13h chain before Windows 95 loaded.
- The hard disk controller in your computer was not detected by
Windows 95.
- The hard disk controller was removed from the current configuration
in Device Manager.
- There is a resource conflict between the hard disk controller and
another hardware device.
- The Windows 95 protected-mode driver is missing or damaged.
- The Windows 95 32-bit protected-mode disk drivers detected an
unsupportable configuration or incompatible hardware.

Ekrisch: What type of computer do you have, how many hard drives and what are they (eg: manufacturer and size)?
ekrisch, haven't heard from you.
With all due respect to John C, be very carefull using Disk managers.

Smeebud makes a good point. You don't want to use a Disk Manager as much as possible. But unfortunately, older systems can't see the entire Hard drive space without using one. And sometimes the Disk Manager that the hard drive comes with basically is what causes your virtual memory to run at 16-bit access. I have encountered this with a 850MB Maxtor hard drive which I was running on my 486-66 before I eventually upgraded to Windows 95.
I had the same problem. I solved it by reinstalling Win95.
Open your system.ini to the [386Enh] section. You should have a line that reads as below; If not, add that line, reboot and report the results.
