Hi, Basically, Solaris just keeps BIOS settings. But if bridges or devices are detected to be I/O or MEM access disabled(either because they have invalid address or are disabled in command), we'll try to re-program them with valid resources.
And per my understanding, Solaris doesn't have limitation for MMIO size.
