Welcome to FreeDOS

MGRX is a 2D graphics library derived from the GRX library. MGRX supports DOS using DJGPP (with djdev 2.05, gcc 7.1.0) and supports VGA and VESA compliant cards. Global dependencies, for all platforms, are libjpeg for reading and writing JPEG files, and libpng and zlib for reading and writing PNG files. MGRX is distributed under the GNU Library General Public License, with amendments - read copying.grx for details. You can download version 1.5.1 from the MGRX website. Read the changes.txt file for the full list of what's new.

Zerofill writes zeros on the empty disk space for the selected drive. It can help virtual machine and disk compression software to better compact the allocated space in the volume, and so on, reducing its disk usage. Javier has released Zerofill 2.01 with several new features: + Support extended FAT32 drives with 7305 DOS service if available + Increased speed by generating temporary 1GB files (instead of 500MB files as in previous version) + Changed temporary file naming convention + Added a question to confirm deletion of temporary files + other smaller code updates. You can find it on the Zerofill web page.

If you're following along with the latest development tools, you may be interested in JWasm, a MASM-compatible assembler. Version 2.19 was released today and includes several bugfixes and other changes. A few highlights: format mz: stack segment was never written, format mz,pe: start offset for first segment may have resulted in an invalid binary, write listing reworked, PUSHW will emit warning "magnitude of offset exceeds 16-bit" if operand is a 32-bit offset, and using 'option oldmacros' will cause a warning only. You can find it at JWasm on GitHub, under release v2.19. We've also mirrored this in the FreeDOS Files Archive at Ibiblio, under /devel/asm/jwasm

7-Zip is a file archiver, and Darik Horn's Retro7zip is a native backport of 7-Zip for DOS.

You can download the new 7-Zip at the retro7zip GitHub.

Bernd has released FreeDOS FDISK 1.4.2 with several important fixes. See the change log for a full list of what's changed. Highlights include: Prevent FDISK from accessing and modifying partitions with more than 23 logicals defined, fix bootloader trying to boot from an active partition not containing a valid volume boot record, and only complain about an unusable extended partition if there is any defined (not when there is no extended at all).
