[gPXE] Setting delay time to boot

[Fatih Tolga Ata]

Hi,
The OSes in my san servers boot slower than the remote machines which 
boot from iSCSI targets. So, the remote machines can't boot because 
iSCSI targets are still booting at this time. So if I want to restart 
san servers, I have to go to the server room to restart the all remote 
machines. So, is there any command line option to delay the booting? 
I've looked at this page http://etherboot.org/wiki/commandline . But I 
didn't find any info about delaying.

Regards.
