First, the HMC no longer has DVD drive. Second, there is no more HMC as separate machine. There is a HMA - still the same Trenton Systems PC server working as both HMC and SE. And of course it is inside CPC rack, at the top (A42 and A41). To complement, the ZZSA is IPLable, but it is not z/OS. Depending on your setup I'd suggest some small tech LPAR. Much more convenient. -- Radoslaw Skorupka Lodz, Poland W dniu 06.03.2025 o 22:33, Jerry Whitteridge pisze: > Yes - I used to keep a CD/DVD of the ZZSA standalone system on the top of all > my HMC's.
