I wanna install slackware9.1(sw9.1) via NFS method but failed ....

the NFS Server :
I extracted all files from the two install-ISO files of sw9.1 in /iso/tree,and start NFS Service:
I test the NFS Server is ok!


the Client box:
I started form CDROM of sw9.1 install cd1
my partions had completed.
selected NFS install method,set NFS Server pointed to 10.10.10.1:/iso/tree
then, I find install package options appeared on screen,
I selected FULL INSTALL, then install had start.
but less one minute,prompt install had completed!!???

what's wrong with my work??
pls help me.
thanks for any reply

Just to make sure, client IP is 10.10.10.1 right ? When you gave the NFS server IP, did
you indicate 10.10.10.1 ? If yes, it is wrong

I would think the better is to set /etc/exports in NFS server like :
/iso/tree 10.10.10.0/24(ro,sync)

very sorry, that is a clerical error.
My NFS Server config file is:
/iso/tree 10.10.10.0/24(ro,sync)


my client IP is 10.10.10.10

thanks
