Re: W98SE MCA Adapters

Windows manipulates the registry, not the driver.

The driver may not, but what of the .INF file? It does.

The INF file defines the operational parameters. Conflicts can be easily
caused by an INF file.

I have no reason to believe a machine that was working flawlessly with
a relatively fresh installation of Windows, and running with only one
other program installed would have a truly corrupt registy.

I don't think the machine had a corrupted registry. You got a conflict after
you installed the driver and Windows issued a standard error message. You
reverted back to the original driver and the conflict disappeared.

The same INF file worked on tested installations so far, but it did not work
on yours, that was the good side of your tests. Windows versions had
changing requirements, one probably needs 4-5 test machines running
different W9x versions to validate the install procedure and driver
operation.

I did a new build but could not test the changes. The floppy drive on my
test machine, Mod. 77, suddenly refused to read diskettes.

A bug in the original sense of the word. Children can be very
imaginative....


The only difference now being that...everything works. I've got a
brilliant
800x600 display at 64K colors. Windows and the display properties window
are
perfectly stable--I've been running it for a while now, doing everything I
could think of at the time. Nothing seems to be throwing any
problems--even
switching to and from a full screen command line within Windows works,
whereas before it would cause a total lockup.

There is a new setting in the XGA2 section of the INF file and two other
changed settings. I'll have to completely rework a part in XGA2.DRV, it has
been done very poorly and incompletely. It is this part that is causing
troubles and reboots on mode and color depth changes. I saw that the S3 code
handles that much better - but it has been written by S3 and not M$.

800x600 at 64K colors is set to the default of 72 Hz in this release (April
28), it uses the IBM monitor mode settings (75 Hz used Sony settings).

I have not yet tried twiddling with scan rates or anything like that. My
monitor is working (still can't find a VESA type display in the Windows
display list--is that where I should be looking?) with the IBM G50 model
selected.

No need to change if it works. The VESA type should be behind a Standard
Monitor / Super VGA, select at least 75 Hz and 1280x1204.

I've also seen no problems with odd colors at startup.

Not yet fully eliminated, in 800x600 and 640x480. It looks rather like a
slight disorder in the XGA mode settings although I've strictly followed the
techref (the orginal driver did not). This does not happen in 1024x768.

There is another known problem, font corruption in 1024x768 with 16 colors,
at least on this installation. Please check that.
