|Looks like you're going to be tight with details. You could look here and see if anything applies:|
Post back specs on the system you're installing 98 on--cpu, ram, hard drive, etc.
Is this a stand-alone install or maybe a dual boot situation with another OS or an install as a virtual machine?
Are you booting from the 98 cd or floppy bootdisk?
At what point in the 'trying to install' process do you get the error?
