|There is no such thing as a 1.05GHz Sempron...you're running your CPU at the wrong speed. All Semprons run at 333MHz FSB (166MHz frequency) so your CPU is probably supposed to run at 1.75GHz (10.5 x 166MHz). Get that straightened out before doing anything else. Go into the BIOS & change the CPU frequency from 100 MHz to 166MHz. Save your settings & exit.|
I suggest you go with the dual boot setup, not VM. Start by wiping the HDD, then create at least 2 partitions...one for 98 & one for XP. If you want 98 to be able to access the XP partition, both partitions must be formated as FAT32. And it's almost always best to install the older OS 1st.
Install Win98 on the C: partition. Make sure you have no more than 512MB RAM when doing the installation. After 98 is fully installed with all drivers & updates, tweak the vcache settings so that you can use more RAM.
Once that's finished, boot into 98, then pop the XP disc in the drive. When the screen pops up asking if you want to update, select "Advanced" & direct XP to install onto the 2nd partiton.
That's all there is to it.
BTW, that's a horrible motherboard you got there.
