Really? Having an apoplexy because someone paid for one of R. Loew's patches and had success?
OK. You asked for it. I was going to sit this one out because I have no experience with PCI-E cards and didn't have anything to add, other than maybe a few links to MSFN, where others are tackling these issues, and looking for RESULTS, not for foolish "why" questions.
I applaud your answer. And I wish you success.
However, you've certainly NOT come to the right place for help in your quest.
Here you will find only two types of "help."
There exists one set of posters who do genuinely mean well, but have their minds set that Windows 9x is only usable on P3 hardware and earlier, and have the idea that 256MB of RAM performs better than 512MB. These are nice guys, just set in their ways, but they will generally always recommend that you "downgrade your hardware."
Then there exists the other set. This group is a particularly arrogant set, who always want to know why you want to use your own computer the way you want to use it. They act offended if you want to attempt something outside the mainstream of current Microsoft dogma. This group's default answer is always "upgrade your OS and run a VM."
This group likes to go around voting down the posts of people with whom they disagree, even when said posts have been chosen as "Best Answers" or have solved other poster's problems.
This group likes to refer to Mr. R. Loew's patches as "hacks" because he has dared to spend his time working on something that Microsoft has discontinued, and has dared to produce products that allow Legacy systems to run on hardware where they normally could not.
If you want real help with this, rather than having your time wasted by rubbish like the above, then go to MSFN, where we have an active, friendly, and helpful Windows 9x community.
