I was planning to boot off a wireless NIC through PXE. Is it possible ?? Thank you for your time.. -- thanks and regards, balaji rao ^ permalink raw reply [flat|nested] 6+ messages in thread

There are some, although many of them are old: adm8211, airo, ath5k, rtl8180, rtl8187, and some of the rt2x00 devices. > I was planning to boot off a wireless NIC through PXE. Is it possible ?? The gPXE (formerly etherboot) project seems to support PCI-based (e.g. cardbus, but not PCMCIA) orinoco devices. I cannot verify that, since I have no such device (donations accepted!)... Hth!

Just to set the record straight, I'm unaware of any CardBus devices compatible with the orinoco driver, i.e. Prism 2-3, Symbol Trilogy or Hermes I based 802.11b device. At the first glance, gPXE appears to support Prism chipset only, either native PCI or PCMCIA behind PLX9052 bridge. -- Regards, Pavel Roskin ^ permalink raw reply [flat|nested] 6+ messages in thread

I'm not sure where you are looking. I have a git tree from here: git://git.etherboot.org/scm/gpxe.git The gpxe source file src/drivers/net/prism2_pci.c claims to support PCI ID 1260:3873 which is listed as a prism 2.5 device supported by drivers/net/wireless/orinoco_pci.c in the linux tree. Similarly the gpxe src/drivers/net/prism2_plx.c claims to support all of the PCI IDs listed in drivers/net/wireless/orinoco_plx.c from the linux tree as well as one that is not listed there (126c:8030 -- perhaps we should add it?). As I said, I do not have _any_ pci-based prism2-3 hardware (donations welcome!), so I can not verify whether or not the gpxe code (or for that matter the linux code) actually works -- YMMV. I'm just going by what information I have. John -- John W. Linville linville@tuxdriver.com ^ permalink raw reply [flat|nested] 6+ messages in thread

The code in prism2.c looks similar to linux-wlan-ng, which is Prism-only. But on the other hand, the gpxe driver offers only very basic functionality, which doesn't even include WEP, so it's possible that non-Prism cards would work. -- Regards, Pavel Roskin ^ permalink raw reply [flat|nested] 6+ messages in thread
