Configuring winBoot/i
First of all, you need to install and activate the winBoot/i Server. Until
activated, the winBoot/i Server will display an error message on winBoot/i
clients attempting to connect to it. Please refer to the emBoot documentation
on how to do this.
At the second step, you need to configure the winBoot/i Server services.
Launch the winBoot/i console and start the emBoot PXE, TFTP and winBoot/i
services. This can be done by clicking on the Services node in the left-hand
panel and then double clicking the specific services listed in the right-hand
panel. Refer to these chapters of the emBoot help guide: Configuring the
emBoot PXE, TFTP and winBoot/i services, Implementing emBoot PXE
Service and DHCP on the same server, Implementing emBoot PXE Service
and DHCP on different network servers.

At this step, you need to create an iSCSI boot volume. Login to the winBoot/i
Client machine, launch the Computer Management console and select Disk
Management. Initialize the disk, quick format it, set partition type as
“primary”, provide a drive letter and mark partition as “active” (a complete
step-by-step description is provided below in the Initializing StarWind disk,
formatting it and marking as “active” section of this manual).
Use the winBoot/i System Copy utility to copy the operating system to this
newly created drive (see the Copying operating system to the newly created
boot volume section of the manual below).
Now you can try to boot from the iSCSI volume to verify if everything is OK
with the machine. To do this you need to enter the winBoot/i Client computer
BIOS and enable PXE boot (also referred as boot from LAN or boot from
network).
Save the settings and exit the BIOS configuration utility. Check to see if
machine can successfully boot from the iSCSI volume.
