hello everyone, i have an nforce based desktop pc running windows xp pro sp1. it has a 25pin parallel, 9pin serial, 4 usb 1.1 ports, no ethernet card or firewire, with other standard stuff. I recently got a compaq presario 2517at laptop which runs windows xp pro sp1. it has a 25pin parallel, 3 usb 2.0 ports, 1 firewire, no serial port. i want to transfer data from the desktop to the laptop and vice-versa. basically i don't want to sync data..but transfer. how do i transfer data at legible speeds? i've heard of interfacing the two thru parallel as well as usb ports. i'd prefer usb. in that case, what cables do i need? what additional software would i need? what would be the approx cost? and how do i got about setting up everything? second Q: do all hp printers come with built-in infra-red connectivity? i also have hp deskjet 920c printer. but it wasn't detected by the laptop. third Q: with what category of graphic chips (geforce series) can the ati radeon igp 345m be compared with? where do i get its updated drivers? the catalyst drivers ain't getting loaded as they are not for igp series. waiting for a reply........thanx in advance.
