net boot linux still has problems!!!

[Gavinux Li <linux4sparc@yahoo.com>]

After 2 days of hardworking, I still can make my IPX
boot from network.
I tried 3 different tftpboot.img 
   one came from ftp.debian.org ftp version potato
   second came from ftp.debian.org woody
   third came from
http://auric.debian.org/~bcollins/disks-sparc/current/...
All these image hung just after display 'Booting
Linux...'

Here is the details:

I use null modem cable connect my PC to IPX to try net
boot and install debian
my IPX has no keyboard, no monitor.
my PC is running Redhat 6.2, I installed DHCP server,
rarpd, tftpd, nfsd in it. I didn't install DNS server.

I edited /etc/ethers add:
08:00:20:aa:bb:cc sparc

I edit /etc/hosts add:
192.168.1.10 sparc

/etc/inetd.conf contains:
tftp dgram udp wait root /usr/sbin/in.tftpd in.tftpd
/tftpboot


I got linux-a.out for sun4cdm and put it in /tftpboot
I made a symlic link by:
ln -s linux-a.out C0A8010A.SUN4C

I got root.tar.gz and untared it to /tftpboot/, it
creat a directory debian-sparc-root
I made a symblic link by
ln -s debian-sparc-root 192.168.1.10

I edit /tftpboot/debian-sparc-root/etc/fstab, goto the
end and add:
192.168.1.1:/tftpboot/debian-sparc-root /  nfs default
0 0

I add a statement to /etc/exports
/tftpboot/debian-sparc-root     sparc(rw,
no_root_squash)

I reboot my PC, everything is [OK]
I started minicom, power on IPX
When my PC display the IPX is checking memory, I send
Ctrl-A F , then IPX goes into boot prompt status,
the I issued command

ok boot net
nfsroot=192.168.1.1:/tftpboot/debian-sparc-root

It displays:

Boot device : /sbus/le@0,c00000   File and args :
192.168.1.1:/tftpboot/dt
