Nope, it doesn't bypass -- USB is still USB, apparently. In fact my add-on card (added since the board doesn't natively do USB3) was the first set of ports to fail. > > > KM> Right now it's hosting the old original > KM> PCLOS setup, which gets used as the #2 channel for summer > KM> baseball ... > > Better hurry: football season is starting! Not at my house... Football is the poor relation, and it's become so structured and predictable that it's no longer interesting.

So I decided must be the case, tho it's not universal -- common enough for laptops to be able to display own screen and out via a port. Tho not sure how it's set up -- but I've seen laptops that insist they have both onboard and dedicated video, and both work simultaneously. Which would be the same situation as with the Dell -- it has both. But maybe not the required BIOS function. Next time I reboot (silly kernel updates) I'll have to look in there. þ RNET 2.10U: ILink: Techware BBS þ Hollywood, Ca þ www.techware2k.com --- QScan/PCB v1.20a / 01-0462 * Origin: ILink: CFBBS | cfbbs.no-ip.com | 856-933-7096 (454:1/1) .
