Image description: A logo, consisting of white on black text that reads "SFP CORONA Version 0.1". There is also hard-to-read dark blue and dark red text, reading (blue) "Microsoft (R)" (red) "MS-DOS 7.10" (blue) "Copyright (C) Microsoft Corp. 1981-1999". Image description end.
This file, saved as an appropriately sized .bmp file, was a boot logo for the DOS logo mechanism. We created it for use with the Corona Core distribution that we intended to create, based around extracting MS-DOS v7.10 from MSW 98SE (with a license key to allow doing so of course). This file was found in a directory named 2010-01-11, and carries a modified date of 2008-01-10.
SFP is the old "organisation" for our work, standing for SF Productions. Corona Core was named for the outermost layer of a star's atmosphere, visible during a total solar eclipse (Sonnen-Finsternis). Not related to the beer brand or the type of virus. Later, we envisioned Corona CoreNT which would be a set of utilities to be used with MSW NT-based operating systems.

Today I added a review of the current iniload's control flow. Specifically, this is for the lDOS entrypoint and doesn't trace into subfunctions such as error, query_geometry, read_sector, check_clust, clust_next, clust_to_first_sector, nor the multi-sector loader.
