[syslinux] looking for info using memdisk to load an image via pxe and/or undi network driver

[David Meltzer]

hello and thanks for reading this,

i have a computer with pxe support.
so far, i can load a .img from a cdrom using memdisk.

now, i would like to try to get the .img from the network.

i say this quote from the page
http://syslinux.zytor.com/pxe.php
"Normally, PXELINUX will unload the PXE and UNDI stacks before invoking the kernel. In special
circumstances (for example, when using MEMDISK to boot an operating system with an UNDI network
driver".

also
http://syslinux.zytor.com/faq.php
"The argument 4 will perform a local boot with the Universal Network Driver Interface (UNDI) driver
still resident in memory. Finally, the argument 5 will perform a local boot with the entire PXE
stack, including the UNDI driver, still resident in memory"

i cannot find more info on the website or on the internet at large.
has anybody done this.
can you share a few details.

also, please keep in mind that i am booting mswindows98 via memdisk.

thanks,
dave
