Set IRQs as follows: 4- Com1 Serial Mouse 3 - Com2 - for PicStart 5 -Com3- for modem 10-sound card 7- Printer 9- for LAN card If have problems reassigning IRQ you may want to use the following: -remove cards and install them one by one -reserve IRQ in Device Mgr. -Properties. This one helps to change IRQ for Video card if you have PnP BIOS. It really works fine.
