Syslinux - Aug 2011 - Problems booting WinPE ISO

I have set up a RHEL 5.7 PXE server and trying to get a WinPE ISO to work.
Currently PXE seems to handle the image properly but the process stops after
Loading boot sector... booting... Full list of what is going on.

Ramdisk at 0x72b9c00, length 0x0a680000
command line: iso initrd=../images/windows/winpe_x86.iso
BOOT_IMAGE=../memdisk

Disk is hard disk 0, 170496 K C/H/S = 340992/1/1
Total size needed = 2091 bytes, allocating 3K
Old dos memory at 0x9bc00 (map says 09c00), loading at 09b00
1588: 0xffff 15E801: 03c00 0x71b9
INT 13 08: Success, count = 1, BPT = 0000:0000
old: int13 = f000827c  int15  = f000cebe
new: int13 = 9b000008  int15  = 9b000290
Loading boot sector... booting...

I burned the WinPE ISO onto a CD and was able to boot the server fine.
I'm using syslinux.x86_64 3.11-4 that came with RHEL 5.7

For me often the 'iso raw' options work. Windows is a protected mode 
operating system (as most modern OS's are) so you'd need some kind of 
mass storage driver for Windows to recognise the ISO.

I think the Syslinux wiki mentions MEMDISK and the WinVBlock driver.
[ http://reboot.pro ] is an entire forum dedicated to booting Windows, 
Linux and DOS in various ways (network, memory, USB etc).

Boot.kernel.org , ipxe.org netboot.me also offer some internet-based 
options, but that's unrelated to your subject likely.

You need the ISO parameter
http://syslinux.zytor.com/wiki/index.php/MEMDISK#ISO_images requiring
at least 3.84 and probably other adjustments
http://syslinux.zytor.com/wiki/index.php/MEMDISK#Windows_NT.2F2000.2FXP.2F2003.2FVista.2F2008.2F7_.28NT_based.29

You didn't report your MEMDISK version, but it appears to have been too 
old.  The 'iso' option should not have resulted in "Disk is hard
disk
0".  - Shao
