The z/OS IPL process is highly dependent on SYS1.NUCLEUS and the LOADxx data set being Partitioned Data Sets, and on doing non-sequential accesses to them. There is no way to IPL z/OS from anything other than a device which emulates the ECKD DASD architecture.
Jim Mulder (retired from z/OS Development) . >>>ZNETBOOT might help. I wrote ZNETBOOT for to help Linux people (who don't know VM, especially CMS) to start an installation from just a single configuration file. The design is: fetch a kernel (using 'wget' or 'curl', all under-the-covers), also fetch an INITRD (maybe), stack the multiple files into your reader, then IPL 00C. Now ... I confess ... finding a z/OS nucleus which can be dropped into your reader ... I have no idea where or how or if it's even possible. (But one can hope.)
