I have downloaded and extracted Syslinux-4.03.zip to my C drive from
http://www.kernel.org/pub/linux/utils/boot/syslinux/


extract "gpxelinux.0" and put it in the tftp-root directory (I use TFTPD32,
by the way: http://tftpd32.jounin.net). gpxelinux.0  contains both (gPXE and
the pxelinux.0). This way your PXE-clients can afterwards boot from http
(faster!!)  instead of tftp. gPXE-clients can do that natively.

also create a "pxelinux.cfg"-folder inside your tpft-root-directory.

put the (plain text) file "default" into this .cfg-folder. it should contain
at least:

default linux
prompt 0

label linux
 kernel vmlinuz
 append ramdisk_blocksize=4096 initrd=initrd root=/dev/ram1
ramdisk_size=1000000 console=ttyS3 debug=off splash=silent vga=791

or something like that.

Now your clients (PXE-clients as well as gPXE-clients, if you have done the
chaining-trick) should try to load "vmlinuz" and "initrd" from  the
tftp-server's root.
Because I want my clients to get these files not from tftp but from http
(Windows IIS-Server, a Web-Server), i modified the "default"-file:

default linux
prompt 0

label linux
 kernel http://192.168.2.1/vmlinuz.xtp
 append ramdisk_blocksize=4096 initrd=http://192.168.2.1/initrd.bin
root=/dev/ram1 ramdisk_size=1000000 console=ttyS3 debug=off splash=silent
vga=791

I gave these files the extensions ".xtp" and ".bin", because of the
http-server's MIME-types. (It must be "binary/octet-stream"), when I copied
them to IIS-"wwwroot"-directory.

gPXE-clients also can get the "pxelinux.0" from the http-server, if you
configure the boot-server option in your DHCP-Server.




What do I do next? Am I right in assuming that by my http-server, you mean
the 2003 Terminal Server (in my case)?

no, i ment the IIS-Web server (WWW)-server (an apache could do the same
thing).




Also you said "This way both types of client can receive vmlinuz / initrd
from my http-server".Where will I find the vmlinuz/initrd and where do I
install this? i.e does it go into the tftproot folder?

They are part of the SYSLINUX-package, but are also created by TS-O-MATIC or
by the thinstation build-environment (Folder boot-images/PXE)

put them to your "wwwroot" or tftp-root folder (preferable wwwroot of
http-server)
