Turns out that I did not have a corrupted ISO file and tftp-hpa is not
at fault. I had saved the winnt.sif file in a unix format and for
reasons that are not clear this was producing the error message telling
me txtsetup.sif is missing or corrupt. One would think the parsing of
the file would cause the inability to locate the ISO file to be
downloaded since that information is the last line in the file.
Thanks for the suggestions and help. This was an odd problem. I guess I
kinda shot myself in the foot :(

I am not using memdisk. Windows 2003 SP1 supports booting ISO from a
ramdisk. If you place startrom.com, NTLDR (setupldr.exe renamed), an
appropriate winnt.sif
[SetupData]
BootDevice = "ramdisk (0)"
BootPath = "\i386\System32\"
OSLoadOptions = "/noguiboot /fastdetect /minint /rdexportascd
/rdpath=pebuild.iso
file with the correct parameters and the ISO file (BartPE using W2003
SP1 source) into the root of the tftp server you can boot an Windows
2003 SP1 based ISO from ramdisk.
After updating to the latest available ebuild of tftp-hpa on my gentoo
box I appear to be able to download a large file with no problems to
another Unix box but the M$ tftp client bombs after 33,553,920 byes
everytime. Perhaps the M$ tftp client implementation has some sort of
limitation of which I am not aware.
My next real issue is the fact that the ISO file begins to load and
tells me txtsetup.sif is missing. So I don't know if the ISO is
corrupted or not. The same implementation on a M$ tftp server works
without a hitch. I guess I will need to do a packet capture and look for
any hiccups. Although I am not so sure a tcpdump will actually show me a
problem, assuming the file downloads in it's entirety.
Perhaps I should do an MD5 hash on the file and tftp it down and look
for a problem instead?

I am trying to download a 200MB ISO file and each time I attempt to do
so it will timeout after around 30 MB. I've used both a Microsoft and a
FreeBSD tftp client with the same results. When PXE booting a pc and
letting it download the ISO it either hangs halfway through or the ISO
appears to be corrupted when trying to boot to it from ramdisk. I am
looking for suggestions on how to troubleshoot this problem?

You cannot boot cd-rom iso files directly from ram via memdisk - memdisk
only emulates floppy and hard disk images. You need to burn them first
and then boot the burned cd.
