Maybe of general interest. - can't mount a NFS root from a tftp operate loader - can't mount a NFS root froma a BOOTP configured kernel. This seems related to a bug in the loader/kernel kenv. Loader pass a nfsiohandle via kenv without check. If the loader doesn't do any NFS operation, it's a pretty invalid all zeroes nfsiohandle that messed kernel nfsroot mount. - PXE i/o problems. intel PXE i/o is NON_BLOCKING. It is supposed blocking on all the UDP code. Also seems recall a bios I/O buffer configured as a packet buffer. Sorry. I missed to report this (think). -- josemi
