Hi, I've encountered problems booting hirensbootcd.ima (DOS version of Hiren's boot CD).
I followed instructions at http://erpxe.org/Hirens_BootCD_(Dos)
but after choosing menu item "Hiren's BootCD 15.1 DOS" erpxe just returns to menu without any error message after trying to load image.
I switched off menu and tried to load image from syslinux shell typing:
/boot/isolinux/memdisk RAW initrd=er/plugins/hirensbootcd/hirensbootcd.ima
and it showed:
"booting kernel failed: invalid argument"
after digging internet for this error message I've found that it is a bug in pre-6.03 versions of syslinux (and in 6.02 on which erpxe is based)
So I downloaded 6.03 and changed pxelinux.0, memdisk and all other modules in erpxe path.
But nothing changed.
I went further and tried version 4.07 of syslinux and it worked OK!
But such old version is incompatible with erpxe menu system and I managed to load kernel only from command line.
So what are the options to load hiren's boot cd? Maybe there are any workarounds?

I'm not sure about version 4.07 with ERPXE but it used to run with version 4.
run the following command on the server: now try booting into ERPXE and see if there is a 'sending NAK (1, File not found)' and which file is missing.

My server is running Windows Server 2003 with its own TFTP service, I don't know are there any logs.

Thanks to syslinux irc chat the problem is solved.
I changed order of parameters
in file er/plugins/hirensbootcd/hirensbootcd.menu
changed
------------------
INITRD er/plugins/hirensbootcd/hirensbootcd.ima
APPEND RAW
------------------
to
------------------
APPEND initrd=er/plugins/hirensbootcd/hirensbootcd.ima raw
------------------
(removed INITRD line and put ima path to the APPEND itself and turned 'raw' lowercase)
