I suspect that if the card were enabled, Etherboot would find it and continue on its merry way. I'm interested in trying this if someone can tell me the magic to enable the card. | | | |-----Original Message----- |From: Robert Thompson [mailto:email@example.com] |Sent: Friday, January 21, 2000 6:28 AM |To: firstname.lastname@example.org |Subject: Re: 3c90x drivers | | | |In regards to PCI PnP: |I may just be blowing smoke here, but I believe that the BIOS PnP setting |controls how the PCI BIOS remembers resource assignments between boots.
