+InsaneMultitasker Posted May 13, 2022 Author Share Posted May 13, 2022 Are there any Geneve users who are wanting to and/or are ready to forgo using a floppy disk controller at CRU >1100 in favor of the TIPI DSK devices? The Geneve device powerup routine is now configured to test for TIPI and if present at >1100, the OS automatically maps DSK1-4 to the TIPI drives. We now working through the OS initialization code, cleaning up some old code and documenting some of the lesser-known internal code with comments. 2 Quote Link to comment Share on other sites More sharing options...

One caveat to removing CRU restrictions is that the HFDC and SCSI cards share the "WDS" names in their respective DSR EPROMs. After deep-diving the OS/XOP/DSR powerups, I no longer feel as strongly about removing the SCSI card's CRU >1200 requirement. The OS powerup routine skips >1200 to avoid incorrectly detecting a SCSI card as an HFDC. And for the detection to succeed without CRU restrictions, the SCSI card would need to be identified first and its CRU skipped during the HFDC detection. (This is how the Horizon Ramdisk CFG program operates). The IDE code incorporates a FIND routine, so maybe we can leverage it for the SCSI and HFDC powerups. I'll give this a bit more thought. Also, it seems that the OS does not validate the presence of a floppy controller so depending on what the OS thinks is at >1100, the IO routines will blindly attempt to use TI, CorComp, or Myarc routines when DSKx access is requested. We'll confirm this and attempt to block the routines if there is no card present. 3 Quote Link to comment Share on other sites More sharing options...

+9640News Posted May 18, 2022 Share Posted May 18, 2022 Dan, In CLI\GETCATS is where the code is: Here's some info: * * do a winchester catalog... * 1) read record zero of "WDSx." to get name, size, free * 2) read dir entries, move the name, creation date * 3) read file entries, * a) set flags * b) set sector count #1 * c) set eof offset if pgm image * d) set record length * e) set sector count #2 (used by pgm image) * f) compress creation date * g) compress update date The GETCATS source file is a very complex source file that got even more complex handling the TIPI since the TIPI could have more than 127 files and more than 114 directories. We had to limit the number of files and directories display for the TIPI, because it buffered that information in the buffer page of the CLI at >8000 to >9FFF, and the page maps at >A000 and up were used for other functions. 2 1 Quote Link to comment Share on other sites More sharing options...

+dhe Posted May 19, 2022 Share Posted May 19, 2022 fwiw -- I've been updating Beery's HD image - when it's good, I'll let Beery and you look it over and then release it. It's got most if not all the updated software and also now has fixed genprog libs. Quote Link to comment Share on other sites More sharing options...
+dhe Posted May 20, 2022 Share Posted May 20, 2022 blob was a big help. I was trying to read through lib-doc of tic (it's a fairly long file) and ran into some none GeneveOS issues. 1) dm does a great job of listing long files, the downsides are you can't page up and you can't search. 2) loading the file in to qde results in a truncated file. 3) Peter Muys Editor locked up when I tried to load the file. Does anyone have a prefered way to read large files, something along the lines of less for linux? Quote Link to comment Share on other sites More sharing options...

Did you use blob from the command line or use the Directory Manager functionality to launch blob with the "Y" keypress? I thought that EDIT stopped loading (and ignored the rest of the file without warning!) if the buffer filled to capacity. Lockup might have been caused by the buffer or by control characters in the file. Quote Link to comment Share on other sites More sharing options...

A lot of the stuff we have from Client came via a file dump called GenSrc.Zip that 9640news got for us from Clint a while back. It appears all of his builds and docs at some point where done on the pc. There is a chance in the text file, a odd character might have creeped in - thanks for the info largest to smallest. Maybe writing a list routine would be a good exercise for me. 1 Quote Link to comment Share on other sites More sharing options...

The ORI of >E0 ensures that bits 7-3 are properly set when combined with the step rate in R0 (in bits 2-0). As for the LSByte >A5, that is almost certainly just 'placeholder' data, since as far as I could tell, only the MSByte of R0 is ever used in this low level routine. (Edit: whether the value is being set correctly via the VIB requires further analysis) 3 Quote Link to comment Share on other sites More sharing options...
+dhe Posted June 15, 2022 Share Posted June 15, 2022 Geneve OS development discussion this can be taken two ways: a discussion on development of the Geneve OS, or a discussion of developing under the geneve OS. Since it's convenient - I'll be taking it to mean the latter, I have a problem or something I don't understand when trying to link with genprog... Yet... LIBR Maint lib_4a symtab shows: And yes, I've discovered when loading files with the linker, you don't get errors, if the files not found or wrong.

+9640News Posted June 15, 2022 Share Posted June 15, 2022 Dan, To date, I do not know of anyone actually using the LIBR capabilities of GenLink. The only thing I can suggest is rebuilding the library from scratch to see if it is a problem with the library file itself, or a bug with the use of the LIBR command.

Programming intent divination for 30+ year old code is always interesting. Instead of moving R0Lsbyte, the code moves the value @CBHA5, since R0 may or may not be properly manipulated due to the error/test logic.

Do you have an example of this? When I run LINK, it generates an error if the object file is not found. The distributed version of $MAKE has some trouble with missing date/time stamps, though that issue has been mostly (completely?) resolved with a disassembly and update to the code. @9640News we'll have to remember to release the updated program file with the next update.

+dhe Posted June 16, 2022 Share Posted June 16, 2022 The ADD command will throw an error, if the file is not found. It's the LIBREF command that doesn't really care what you type! ? I thought I'd be clever and just ADD the whole LIB_4A - and that is accept - but it doesn't work. (I don't care that I had all the routines listed) I think most of my playing can be found below, the LIST command is also very helpful. I also tried renaming LIB_4A to LIB4A - because list inserted a + after _ - maybe that's ok. I don't think libref was implemented in the version of link I have = GenLINK V1.03 ie..
