This MS-DOS Compatability Mode problem wont go.
Posted on 1998-01-12
My system is :-
- i430VX chip set
- Windows 95 V4.00.950a
- 1* Seagate ST32531A 2.1Gb - Primary Master - C:
- 1* Creative Infra 2400 CD-ROM - Primary Slave - H:
- 2* Seagate ST32531A 2.5Gb - Secondary Master and Slave - D: E: F: G:
My MS-DOS Compatability mode problem is :-
Both the HDDs on the secondary IDE port run with 16-bit drivers, if I
physically remove either one of the drives the other goes to 32-bit
drivers. The HDD and the CD-ROM on the primary IDE channel run OK in 32
bit mode no matter what.
I have done ALL the standard things and nothing changes the problem.
- Read and digested the two Microsoft help articles on the subject that
I could find.
- Checked autoexec.bat and config.sys
- Checked system.ini
- Checked for viruses
- Looked of a "NOIDE" entry in the registry, (I dont have one).
- Removed and then re-installed the drivers manually, and automatically
with "Add/Remove Hardware".
- Removed and then re-installed different drivers from the set supplied
on the Win95 CD.
- Downloaded and tried anything I could find on Intel`s web site.
- Done a logged startup. (Drivers loaded OK).
- Looked in ios.log. (Error message was "ESDI head mismatch").
- Cursed a lot.
- Reinstalled windows from scratch.
- Set the BIOS to not auto detect the drives but follow the specs I gave
- I have hunted high and low on the net for a solution, and have tried
everything that was suggested.
I have seen the idea that the i430VX chipset is to blame. How well
accepted is this fact ? If I am going to buy another motherboard to cure
the problem that I am having what chipsets should I avoid ?, is the
i430VX chipset the only crap one ? Got any other ideas ?
If only the operating system was as stable as the bugs that lived in it.
Thanks in advance.
