Microsoft made the source for HIMEM.SYS available to programmers in 1988. "February 7, 1989 Copyright (c) 1988, Microsoft Corporation, Lotus Development Corporation, Intel Corporation, and AST Research, Inc. Refer to the document "eXtended Memory Specification (XMS), ver 2.0" for HIMEM.SYS copyright and warranty information. ... Some programmers may want to obtain the full XMS distribution disk, which contains the source code to HIMEM.SYS, a C interface to the XMM, a test of test programs, and documentation. In the domestic United States, to obtain the latest official XMS release disk, call Microsoft customer service at (800)426-9400 and ask for a copy of the XMS Specification and it's supplemental diskette." yes, it's copyrighted and shouldn't be copied. (btw: the source for himem.asm has no copright mentioned). but most low level programmers that were active in ~1990 (looong before FreeDOS) had already looked at this (including me). and I feel in no way tainted by this. FreeDOS HIMEM.EXE is in no way influenced by my reading of HIMEM.ASM in ~1990. note: source for EMM386 was never published, but leaked to the public in ~2003. Jack probably talks about this EMM386. > When Microsoft released the source code to an earlier version of > MS-DOS (March 2014) source for MSDOS 1.1 and 2.0 is completely useless for FreeDOS design and implementation. and has no HIMEM anyway. BASE >> XMGR > http://www.freedos.org/software/?prog=xmgr > * providing XMSv3 > So we will now need to remove XMGR from the FreeDOS distribution. I don't think so. I took a look at XMGR.ASM. XMGR.ASM is so obviously coded by Jack (judging by coding style) that the claim of a copyright violation would be ridiculous.
