I just decided to grab through my spare/old parts and to put a diskless
486 together.
It just has a NE2000 ('twas SMC before), a VGA card (nothing fancy), some
RAM and a serial port for the mouse (ok, I've cheated, there is also a
monitor and a keyboard :_) )
I've installed the netboot rom and set up my servers to honor the bootp
request.
The rom comes up, reads it's config and loads a special kernel.
I just mounted / from a FR2.0 machine (I know that this won't work, but
I'll fix it when the problem is gone).
The "swap" file resides on /var/swap[/swap.x.y.z.a]. I found out, that
I have to create it by hand, else the rom won't load the kernel. I still
don't know if the file must have special contents or special length...
As I said before, the kernel loads ok and shows that he has mounted / and
/swap with nfs.
Then things turn out bad :-(
The boot screen looks like:
...
npx0 on motherboard
NFS SWAP: 194.39.213.1:/var/swap
using 4096 kbyte. # ok, a little small, but just testing
NFS ROOT: 194.39.213.1:/
vnode_pager_input: I/O read error
vm_fault: pager input (probably hardware) error, PID 1 failure
exec /sbin/init: error 8
exec /stand/sysinstall: error 8
init: not found
panic: no init
... (now it reboots after 15 seconds)
I've tryed many variations of the swap file. I've browsed through the kernel
sources and added some printfs at the critical stages. The filesystem is
mounted properly, has rw access, the file is there and writable.
I bet, I've made a simple and stupid mistake...
can somebody point out my errors ???
