Can not boot RHEL 7.3 by using iPXE

I have been struggling to get my CentOS 7.4 1708 to PXEboot successfully ultimately to proceed to KickStart - using a VMware ESXi VM (BIOS and not EFI). Like this thread, both the CentOS's pxeboot initrd and vmlinuz files are being loaded via HTTP but vmlinuz fails to complete its boot due to not being able to mount the root filesystem.

I note that "mathp" says he/she had success with iPXE and "stock" Centos 7.4.1708 installer kernel. I would appreciate a snippet of the iPXE script that did this so that I can confirm my environment.

Thanks

This is the only way I can get a VM with UEFI to boot CentOS 7-x86_64-1810. Hope this helps.
Also, it will look like it's stuck, give it time. Probably a good 10 minutes or so. Eventually it will load the installation menu.

Code:

set    repo        http://mirror.centos.org/centos-7/7/os/x86_64
set    imgargs    initrd=initrd.img inst.repo=${repo} nomodset

kernel ${server}/${centos}/vmlinuz ${imgargs}
initrd ${server}/${centos}/initrd.img
boot
