I've tried:
"chain memtest.0 4pass onefail && set memtest GOOD || set memtest BAD "
"chain memtest.0 fourpass onefail && set memtest GOOD || set memtest BAD "
but no luck,
any suggestion is appreciated.

There is no such option, and it don't make much difference from a diagnostics point of view, you can run 100times and still not get any errors, but get one at run 101, and you could also get one at the first run and not ever again. (cosmic radiation might even cause this)
If you would like to run it multiple times I would suggest that you restart memtest 3 times with a counter in the iPXE script instead.

If you really want "fourpass" to exist then you can easily add this to the sourcecode, see https://git.ipxe.org/people/mcb30/memtes...ain.c#l330

And finally I would like to mention b800.org which i created for logging the output from memtest, for example see: https://b800.org/using_ipxe.php (There is also a few screenshots on the page)

initial support for building memtest.0 for the 501 version was added in https://git.ipxe.org/people/mcb30/memtes...215a5b9ec9 so you need to check out the pxe501 branch of the above repo
