I have an IO V5, I've upgraded using a BIOS from BadFlash, added a 510Meg IBM HardDrive(just to get started) and got Win98SE up and running no problems.
In my autoexec, I have the IDE and USB PCI hacks to solve problems in those areas, and I've got the IDE controller set to primary only.
Its got a Rise 266 chip in it and 64Meg of Ram.
Additionally, I have a LinkSys USB network adapter, which works great, I can transfer files to and from my other boxes.
When the machine is idle, the CPU is running at about 25% or less.
My problem is that when I play an MP3 using either Winamp or MP71, the processor usage maxes out at 100%, the playback runs slow and stutters etc.(the MP3 is on the hard-drive, not across the network)
If I pull out the Network Adapter, as soon as Windows Clicks & Whirrs and realises its gone, CPU usage drops right down and the MP3 playback is smooth.
According to System Devices, there are no conflicts.
I've got the VIA sound drivers installed (dated 8-31-2001)
When the machine boots, the windows startup sound plays smoothly.
With different USB device installed, such as my WebCam Go, the playback is fine.
I've tried alternating between TCP/IP and NetBEUI, it makes no difference.
Running netstat whilst this is happening, doesnt show any connections, so its not like Winamp is doing any network stuff.
I've been through the tech forums on here (where I dug up all the various tips mentioned above) but I can't find an answer to my specific problem.
Does anyone have an ideas about the cause of this?
