Hi,
When "chain http://192.168.1.10/Win2019Core.vhd" , the system display the
following message: Input/output error (http://ipxe.org/1d0c6239).
Win2019Core.vhd is about 10GB.
Please thanks for helping!

I don't think the http stack currently support that large files.
I came across the same problem some weeks ago and solved it
by using a 64-bit build of iPXE: As pointed out by Michael,
those can be built with
make bin-x86_64-efi/ipxe.efi
make bin-x86_64-pcbios/ipxe.pxe
I've also made patches for 32 bit to support images over http
larger than 2 GB (in theory up to 2**63 bytes, tested with
a 32 GB image), if you really need 32 bit support now you can
apply those patches for now:

(@Michael: sorry for the long delay, I promise to try what you suggested
this week and get back to you).
You should find some other way to load your disk, iSCSI for example.
Currently, the only way to support diskless Windows clients I know
of is iSCSI (there might be others). As Christian Nilsson pointed
out, Windows only loads the neccessary kernel, drivers and registry
hives in the early boot process and eventually a Windows driver must
provide the System Volume somehow. Just as with Linux (and other
Unices), if the System Volume / root device is not present the
kernel BSODs / panics.
We are, however working to support boot device as DRBD device (for
diskless clients) for our (Linbit) WinDRBD kernel driver (see
https://github.com/LINBIT/windrbd) and will probably have
something useable in a few months. In our solution you would
boot Windows via iPXE and http from a DRBD device (with a small cgi-bin
wrapper) and once Windows is booted, provide the Windows System Volume
as a regular (Diskless Primary in DRBD speak) WinDRBD block device.
That way you can have setups with redundant servers as well.
What exactly are you trying to build?
Cheers,
- Johannes
