Trying to reach 1993

Trying to boot yet older Solaris/SunOS version: Solaris 2.3. According to the Wikipedia, it's the first one which supported SPARCStation-5. You may wanna ask "what is about SunOS 4.1.4 (Solaris 1.1.2), it can be booted, and it must be the older?". No, it's not. Looks like Solaris 2.x and SunOS 4.x were developed independently: 1.1.2 was released in November 1994, and 2.3 was released in November 1993. Is a bit misleading. But explains why 2.3 has problems with the esp scsi controller while 1.1.2 doesn't. And the both systems are so old that the kadb debugger can't set deferred breakpoints. Anyway, the current status of Solaris 2.3:
