Hallo Bart,
Well if I claim I can get it under 64K I'm not lying.
Did I say you're lying?
OW compiles *plain 2035* as 66318 bytes uncompressed for me for FAT32/386. Why your kernel is bigger after all these optimizations is a puzzle. I've read that on low memory machines its optimizer may be limited
I have 256 MB RAM and 60 MB free XMS (the rest is for a XMSDSK) - surely enough for it.
but I can't think of anything else.
What version of OpenWatcom are you using? I use 1.2. I can't otherwise explain the size difference
For the unstable branch it's 64700 or so.
Even after reducing kernel size with my latest patches I still get 65830 bytes. That's more than a kilobyte bigger! How can we explain that?
Changing the calling convention to #pragma aux default parm [ax dx cx] modify [ax dx es fs] in portab.h (careful, don't do that for SYS & EXEFLAT)
Unfortunately this causes compile errors as early as in dsk.c for me, so I can't use it.
and making LoL (init-mod.h, main.c) extern struct lol FAR * const LoL; (see the const) chops of another couple 100s of bytes.
Adding "const" shortens it by 16 bytes for me, so I added it. Borland kernel size doesn't change.
The smiley implies that it can't be freely downloaded from Vietnam. Maybe you can but I can't.
Why are we so different? I'm much older than you but we both sound like it was the opposite! ;-)
Everything can be physically downloaded.
...if you know the right URL at the right time ;-)
But that's a silly argument and by publically encouraging it you're not doing this project a favour.
Oh, sorry, did I "trod the kitten" again (as we say here)? I'm scared of myself but not ashamed :) Why? Because I'm a complete copyright illiterate, or at least ignorant. And I'm too old to change.
Right, checking again I see it compresses a SYS file like a COM file. Well with some hand holding (load at 50:100) you could treat kernel.sys like a COM file too. Haven't tried that though.
Let me first achieve your uncompressed kernel sizes with OpenWatcom. I hope you help me with this.
Regards, Lucho
