[1.7.8] Netboot slow, graphics corruption

I have a Late 2012, 21.5-inch iMac, 1TB HDD, that I recently installed High Sierra (10.13).  I am using it as one of three masters on the three main subnets I support.  The only purpose of this box is DeployStudio.  Netboot image was made on this box...

My old 10.11 setup works fine, boots quickly, no graphics issues, can do 15 computers at a time without issue...  The HS computer is another matter.  It is very slow to boot, taking 3~7 minutes.  Once it finally does boot, I have graphic corruption on screen.  It appears like there are three no-longer interlaced "screens" displayed.  (I will try and get a picture)  I have yet to try restoring anything, but this is not workable.  It will probably be another year before we roll out High Sierra, Sierra being the most current (but still in the minority), with El Cap being on 90% of the computers deployed.  Ideas?

Re: [1.7.8] Netboot slow, graphics corruption

Tried to do different Net Boot Images with slightly different properties/options.  None of these worked at all.  After 45 minutes of attempted boot, I gave up and turned off the computer manually.  I am not finding a lot of success with DS created NBI's.  Should I try another method?

Re: [1.7.8] Netboot slow, graphics corruption

10.13 netboot is know to be slow, even slower than 10.12. But my clients usually netboot in max 6-10 minutes (I did not time, but estimate)
Slow graphics is also know issue, most noticably on Mac's with 'better' GPU's. Reason; the .nbi is created from the Recovery HD partition, that only contains basic drivers.

Tip: if you are not restoring APFS, and your hardware does not require new versions of .nbi, keep on using your trusted .nbi.
I have used a 10.11 .nbi to restore 10.12 for a long time, until we got newer hardware that forced me to use 10.12.x nbi's.

update: my MacBook Air 2015 netboots from a 10.13 .nbi  in between 3min39 to 4min20 (to the DS runtime) (separate network),

I have finally got a netboot set that actually boots.  Still slow as hell (6-7 minutes), but a new issue has cropped up.  Will not mount the DS repository.  I have tried so many different configurations, that I am losing track of what I have tried.  I need to get this up and running before November as I will be getting approximately 100 brand new Mac's that I will have about a day and a half to deploy.  I don't have any 2017 machines to test on, so I am using the most current model I have (2015) with High Sierra on it.  I have a few ideas on how to get the other 200 computers in my stable upgraded to HS, I just need to get this damn NBI and Repository to work.
