IOPACK - Compressing MS-DOS 7/8 kernel (IO.SYS) + more (Announce)

In past December, i make automated toolkit for this.
Yes, it is like LZ-DOS (and. unfortunatelly, was forced to use part of code from LZ preloader). But, now it is MORE, than LZ-DOS :)
In short, now is possible call any user code BEFORE jump into IO.SYS.
For example, there is packed (and heavy patched) IO.SYS 7.10 2001 w/o logo, but with integrated font loader and Cyrillic 8x16 font.

Anyone have interest for this toolkit? ;)

IO.SYS from Windows 9x is copyrighted software. Please don't post such links!

Germany (.de) apparently frowns upon even links to such unauthorized copying of proprietary software. So even linking could get him (rr) into trouble, maybe. Perhaps your country is more lenient, but even here in the U.S., it's considered bad.

Anything that you own the copyright to or have permission to redistribute is okay (preferably free/libre, aka four freedoms, aka FOSS).

FreeDOS' kernel is compressed with UPX, roughly 45 kb, not too shabby. (Thanks to Tom and others.)

MS-DOS is somewhat harder to find these days (MSDN??). You can make a system floppy in Win7 Explorer (extremely minimal MS-DOS; also optionally used by RUFUS), but Win10 doesn't include that anymore, allegedly. (Even Win7 will stop Extended Support in January 2020.)

"Just use FreeDOS!" :-P :-D

DOS isn't about why. It's about why not.
