Wyse Automated Deployment

Hello guys, I'm kind of a noob so I figured this would be the community to ask for help!

I have a couple hundred devices I need to give fresh wyse images to, and was wondering if there were any easier ways.

The end goal is to plug in power, ethernet, turn it on, select the OS from the grub menu, and let it go.

I can't use the WMMS as I don't have a windows server, nor do I want these devices to get any sort of database/domain configuration/networking so they can freshly configure them on other networks and WMMS configurations. It may be that WMMS doesn't do any of that config and would be the smartest way to go about it, but as I don't have windows server I haven't been able to test anything. If that's my best bet let me know and I can probably spin up a windows server.

I tried to use PXE to boot to a bootable version of the USB imaging tool, but was unable to get it to look for the image files over the network. It seems to just look for USBs. Interestingly enough, you can network boot to the initial imaging screen, and have only the RSP and image files on a USB, and it'll detect and install the os. 

I also tried to combine the partial .img files into one bootable iso, and use memdisk - no luck - but I think that just loads and runs the os on the ram anyways? 

I'm looking into setting up an HTTP boot, but that would require me to update every device to a new bios version and I think that just leads to more things to automate

Again, any advice would be appreciated

Thanks
