This is the NIC driver for a Compaq Presario 6000 series desktop computer with the exact model number of 6RPXE1.
I searched forever before finally finding this using the motherboard model number below.
Motherboard is a MS-6541 with Intel SB chipset of FW82801DB
Simply unzip file then manually direct NIC driver update to folder you unzipped to. This worked with XP Home.
Hope this helps you from pulling out your hair like I did tracking this sucker down!
