|Apparently your Netvista 6579 is a desktop computer - some details:|
Chipset Type: Intel 815E
Data Bus Speed: 133 MHz
Type: AGP 4x - plug-in card, AGP 2x - integrated,
(OR) AGP 2x - plug-in card, AGP 4x - integrated
Graphics Processor / Vendor: NVIDIA Riva TNT2 M64
Installed Size: 16 MB / 16 MB (max)
( plug-in card)
Make sure you load the Intel Application Accelerator - the 815E chipset requires that in order for the hard drive(s) to run at their max. speed, or at the max. speed the 815E chipset will allow. It's available on the Intel web site. In that case the info about what UDMA speeds the hard and optical drives are running in will be seen when you run the IAA program listed in All Programs, rather than in Device Manager - IDE ATA/ATAPI controllers -Primary or Secondary IDE Channel - Advanced
If all of your ram modules are 133mhz ram (PC133), take a look in your bios Setup to see if the ram is actually running at 133mhz - sometimes in older bioses it defaults to setting the ram speed to 100mhz even if it can be set to 133mhz when you have installed 133mhz ram, and you have to set it to 133mhz manually.
Apparently your Netcore wireless usb adaptor is an el-cheapo product (e.g. $25) that appears to be imported directly from China by vendors who are selling it here - many of the "hits" for it on the web no longer stock it.
There doesn't seem to be a manufacturer's web site for it, so I can't find any support info about it.
Some el-cheapo wireless network adapters aren't compatible with Microsoft's requirements for the built in support in XP for detecting and setting up a wireless adapter, and you must set them up with a configuration program or utility that comes with the adapter.
OR - if the software installation for the adapter installs such a configuration program or utility, if you get a message when you try to set up the adapter with the built in support in XP along the lines of you can't use it because something else has been loaded for the adapter, you probably CAN use the built in support in XP to set it up instead, but you have to disable the adapter's configuration software from loading, or un-install it, THEN you can set it up using the built in support in XP.
e.g. there is often a line in msconfig - startup that loads the configuration program or utility you can disable.
If you do try that, when you have made a change with msconfig, you will see two System Configuration Utility windows pop up as Windows is loading the desktop. If you click on the small square box in the first window to insert a checkmark there, the second window will not pop up, and neither window will pop up as Windows loads the desktop while booting after that.
