To: SIer formerly known as Joe B. who wrote (13531 ) 7/20/2002 11:10:07 AM From: Robert Graham Respond to of 14778 I would be frustrated too. For some reason, I have had almost infinite patience with these computer problems that have cost me valuable time away from the project. Every time I add more hardware or software, I am thinking this may be the time my data corruption problems will show up again. Soon I will be dreaming about a big computer lurking around corners and chasing me down flights of stairs, like that Alien movie. You know, the one that had this animal popped out of someones stomach. I purchased an internal modem card for my PC. Will this be the item that will again cause me much frustration? I am on Windows 2000, so I should no longer be concerned. Instead of all that work I put into debugging my computer, I wonder if I could of have the computer blessed by a priest of a local church? I bet the priest would of blessed my computer with a sizable enough donation to the church. The padre would of has to refrain from throwing around the holy water, since I will need to plug the computer in. Maybe it would have been easier to have the priest exorsize any the bad spirts from my computer? Come to think of it, this would of been the same as removing Windows XP from the computer. The biggest problem for me in building computers has been the sound card from time to time. I found out Sound Blaster at one point in time was producing audio cards incompatible with thier own standard. And thier card would simply not work. I would have to remove the card, and instead I would always ended up by returning the cards for a cheap sound card which worked. I see I have most of the plug-in cards taking the same interrupt number 9. This means when I installed the operating system, I had the plug and play capable OS box checked "yes" in the BIOS. Windows 2000 has a brain dead way of handling extended interrupts. What is happening here is everything is being multiplexed onto interrupt 9 to the APIC (Advanced Programmable Interrupt Controller) which then will remap it to its actual extended interrupt. Some motherboards supports this extended interrupt feature that deals with the situations where there are more cards than available interrupts, including sharable interrupts. Windows XP is smarter in this regard and just maps each card directly to an extended interrupt. This is a much more efficient design. Too bad Windows XP does not work for me. I miss some of its design features. So here are the sme of the features that Windows XP has over Windows 2000: 1. More intelligent memory management 2. More intelligent handling of PNP interrupt mapping 3. Checkpointing and restore feature 4. Rollback of a device driver 5. More efficient use of available resources including a smaller footprint in this regard 6. Enhanced multemedia features 7. Enhhanced features for portable users 8. Enahnced customization of the look and feel of Windows (big woopee here) I am sure there are other new features of Windows XP that are not coming to my mind this morning. It is just too bad Windows XP does not work for me. Bob Graham
