• All hail the Moravian Mystic! (T4 use SCBs during boot)

    From Louis Ohland@21:1/5 to All on Tue Dec 27 06:29:47 2022
    I was innocently minding my own business a day or so ago, and MAJ Tom
    had to tell me that there is a "rough POST" for a few IBM adapters.

    I immediately started to gather kindling and Kerosene to burn him at the
    stake for such blasphemy against the revealed will of God, e.g. the
    normular weg of POSID.

    While reaching for the book of God's Will Revealed, I couldn't prove him
    wrong. Further readings in the Holy Writ on OS/2 control exposed a
    blatant relation between SCSI and SCB, this heretical tome didn't
    document use by the complex of SCB during boot, but it didn't damn
    heretics to burn... Lazy IBM tech writers...

    Further meditation on some of the many facets of God's Will revealed,
    hinted at a linkin park between the enhanced BIOS on T1/T2, the 44/45
    pair, and SCB support/use...

    So, what of this "rough POST"? The SCBs are documented to some level,
    but this rough POST is NOT.

    Conceptually, SCB isn't tied to any particular subsystem. Though, SCSI
    was very likely the primary motivation for its creation.

    But it's not a secret that the two are related. The IBM SCSI Adapter
    techref covers SCB rather extensively: https://www.ardent-tool.com/docs/pdf/SCSI-A_Technical_Reference.pdf

    You mean the POST-resident initialization methods for well-known IBM adapters/planar features?

    To some degree this exists in all PS/2s. It has to... If the system
    isn't configured, the POST must initialize at least the most critical
    systems - base memory, video, and storage. Some machines also have POST-resident init methods for TR adapters to allow for R(I)PL (and
    remote configuration in some cases).

    The implementation differs between systems (and even BIOS revisions),
    but I could make a write up about how it generally works.
