We found some bugs recently which will be fixed first: - int 21.1c should report invalid drives via AL (keep other regs?) News here: DR-DOS modifies BX/CX/DX but not DS for inv drives. - CHS calculations are off by 1 and overflowing (thanks Rayer) If your BIOS has no LBA, this was probably a real pain for you. - the BSS_INIT macro is bogus (thanks Rayer) See below: It is fatal on some BIOSes to not init the BSS... - support for 4 GB files would be easy to add (thanks Christian) Basically "allow all seeks, pass status via extra param in the dos_lseek and remote_lseek calls instead of using the sign :-) - Rayer says there are format string bugs in debug messages (I do not have the list, but some compiler seems to tell?) - there is a DF_NOACCESS / DF_DISKCHANGE / initial DBP and BPB (FAT1x FAT32 confusion) patch to be tested with disk tools(*) Does anybody know why we assumed that all compilers except MS C (which almost nobody uses for the kernel) would init BSS to 0, while at least the often-used OpenWatcom does not? It seems that only the habit of BIOSes to zero-out low DOS RAM on boot made DOS able to boot with the broken macro... (*) Would be good to know a volunteer who has floppy drive(s) and preferably also a virtual or free-for-experiments harddisk so we can make sure all DOS disk tools are happy with the patch! > similar can be said about 'Freeedos 1.1 forever' Progress is mostly behind the scenes: People are busy with packaging zips and translating the updated htmlhelp, for example. A lot of work, so more helpers are welcome... What do you think about the idea to use grub4dos instead of isolinux to boot our CD/DVD? Would still use MEMDISK from the isolinux suite, of course ;-).
