So far it looks like the xl0 boot is correctly getting the right MAC address, so we need to find why it's not getting through to the NFS code. Thanks Tom The dmesg that i sent was from a successful boot via sk0. To post an unsuccessful boot's dmesg , i would have to type everything from the screen. What exactly do you want to know? Do you not have a serial console on this box? I'd like to double-check the NIC lines and the lines around the point it fails. It really should be printing out PXE boot MAC address ..., even on 4.1. Could you also post your exact kernel config file? And finally: it's worth trying this with GENERIC, too, particularly from -current (i.e. a snapshot) since that should be able to do this automatically. I was not aware that GENERIC can also deal with nfsroot. In fact, it works perfect with -stable! The problem shows when i change GENERIC to include root on nfs swap on nfs: [EMAIL PROTECTED] [~/src/sys/arch/i386/conf] # diff DISKLESS GENERIC 42,43c42 #config bsd swap generic configbsd root on nfs swap on nfs --- configbsd swap generic The dmesgs for both cases are attached (installed a serial console :-) ) --Heinrich [demime 1.01d removed an attachment of type application/octet-stream which had a name of xl0-GENERIC-stable] [demime 1.01d removed an attachment of type application/octet-stream which had a name of xl0-DISKLESS-stable]
howto set nfsbootdevname for nfsroot?
Hi list, I have successfully set up a client for diskless(8) booting. However, this works only when booting from the first (onboard) nic. When i use another nic, the kernel still tries to do revarp from the first nic, which fails. sys/nfs/nfs_boot.c offers a possibility to override the default search: /* * Find a network interface. */ if (nfsbootdevname) ifp = ifunit(nfsbootdevname); else search loop ... but where/how can i set nfsbootdevname? The boot.conf(8) manpage talks about passing options to the kernel via set howto. Could i use that? -- Heinrich Rebehn University of Bremen Physics / Electrical and Electronics Engineering - Department of Telecommunications - Phone : +49/421/218-4664 Fax :-3341

you cannot set the nfsbootdevname as a kernel option. it is filled in
by autoconf. for example, pxeboot passes the mac address of its boot
interface and autoconf looks up the matching network interface in
sys/arch/i386/i386/autoconf.c

if (bios_bootmac) {
extern char *nfsbootdevname;
struct ifnet *ifp;
mountroot = nfs_mountroot;
printf(PXE boot MAC address %s, ,
ether_sprintf(bios_bootmac-mac));
for (ifp = TAILQ_FIRST(ifnet); ifp != NULL;
ifp = TAILQ_NEXT(ifp, if_list)) {
if ((ifp-if_type == IFT_ETHER ||
ifp-if_type == IFT_FDDI)
bcmp(bios_bootmac-mac,
((struct arpcom *)ifp)-ac_enaddr,

Hmm, at least in my case this does not seem to work.
I have not much C experience, but should nfsbootdevname not be declared
extern in sys/nfs/nfs_boot.c as well?

I also do not see any output from the printf's above. Maybe
bios_bootmac is not true? NFSCLIENT *is* defined. Config is GENERIC with
root on nfs swap on nfs.
I am attaching a dmesg from a successfull boot from the onboard nic.
