Early November work: lDOS command.com port, WarpLink features with /S, WINUDF redirector comments 2026-11-08 WINUDF redirector comments A new revision of WINUDF's DOS file system redirector was uploaded. I had a few comments: * The IISP header detection now contains a wrong comment, claiming that an IISP header could start with a near jump. As there's only 2 bytes before the downlink field, a near jump instruction needing 3 bytes doesn't fit.

Late October: Future plans, and a few reports 2026-11-01 dosemu2 reports * Question on how multiple LFN Find providers handle concurrent usages of find handle numbers, which may clash because the find handle number space is shared for all of them. (A Find Next or Find Close call doesn't get any information on which drive the handle was generated.)

Early mid October work on serboot, lDOS kernel, lDebug 2026-10-18 This week I worked on the serial boot disk loader application donated by Neil H. Gray, added a few patches to the lDOS kernel, and reviewed over 200 changesets to be then pushed into the default (non-experimental) lDebug repo.

Early October work on ident86, lDebug 2026-10-11 ident86 * Use IBL2 sequential 1 format, only read the label itself rather than the colon or keyword that is matched before or after it. (No corresponding revision of insbound.py was created.) * Use IBL2 sequential 2 format, expand local labels to generate their corresponding global labels.

Mid September work on the debugger, symbolic option, ident86 - fix some errors

Mid September work on the debugger, symbolic option, ident86 2026-09-20 Of note, I finally added three subrepos to the lDebug repo, namely lmacros, scanptab, and symsnip. This allows the makefiles to properly reference the source text files in these subrepos as dependencies.

Mid early September work on the debugger 2026-09-13 This week I mostly worked on enabling different build options for the debugger, including _SYMBOLIC. One fix to the immediate assembler (immasm) also got done. The symbolic option changes to the debugger depend on an earlier change:

Work on LZEXE and alias Extensions for lDebug - created

Work on LZEXE and alias Extensions for lDebug 2026-08-30 LZEXE The changes to LZEXE were initiated because I considered that the last several instructions of the depack stub can overwrite themselves if the stack happens to be at an unfortunate location. I was able to generate test cases that do invoke this behaviour.

Extensions for lDebug comparison (eldcomp) debugging I tried out the eldcomp Extension for lDebug recently to verify that the updated alias Extension for lDebug doesn't contain any observable bugs. Bugs found in and with eldcomp I found six discrepancies around the use of eldcomp this week:

Mid late August work: Multi-aliases - created

ecm (ecm@undisclosed.example.com) — 2026-08-23T16:10:37+00:00

Mid late August work: Multi-aliases 2026-08-23 Most of this week's work was about adding multi-alias support to the alias Extension for lDebug. Multi-aliases are injected into the debugger command loop using the inject handler rather than only replacing the command in the preprocess handler. This allows multi-aliases to consist of any number of commands, from zero to one to multiple. The old style aliases are called single-aliases.

Early mid August work on LBACACHE, and a dosemu2 bug 2026-08-16 dosemu2 A test case and patch so that XMS move destination handles are validated. Without this, an invalid handle (eg FFFFh) could lead to a crash of the dosemu process. Discovered while checking the LBACACHE behaviour on XMS errors, which were induced by overwriting the XMS handle with FFFFh.
