Basicly you have a bootsector pointing to MetaKern, and then MetaBoot is attached/appended to MetaKERN.SYS and reuses metakern's bootsector. That way you could use the metakern.sys file that's located on harddisk even on a floppy without having to regenerate bootsectors. Each metaboot instance pointing to a different FreeDOS kernel file (KERNEL38.SYS , KERNEL40.SYS etc) would be convenient :) "metaboot.bot - boot sector that re-uses the boot sector in RAM, set up for the case where MetaKern is called metakern.sys (So you must use a NEW STYLE MetaKern installation!)" http://ericauer.cosmodata.virtuaserver.com.br/soft/specials/metakern.zip Likely just a matter of changing kernel name inside source code and recompiling with NASM. Some config directive (-D or so was it?) would be more convenient :) -- BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers. Connect with experts.

I'm not sure how easy it's to configure Eric's METABOOT.BOT bootsector file to look for a specific kernel name. The use of this special bootsector is that it modified a memory copy of the original used bootsector so geometry is kept. Convenient in case of resizing disk or copying METAKERN.SYS itself to a different drive, including attached bootsectors. > There is absolutely no need to dig out old dead > 1.0 distro utils from their graves ;-) Depends, we've still not added all the extra utilities that make it worthwile to use DOS.

Okay, it's hard to understand what he wants and why. I noticed that he mentioned MS-DOS / Win9x, so I assumed he meant share that with FreeDOS (which makes more sense, practically, than otherwise). There's really no reason to run FD 1.0 and 1.1 side-by-side. Presumably you don't want to run separate (old) utilities from 1.0 anyways. So that part should stay the same, IMO. So basically you're only sharing the kernel, but even that (in theory) shouldn't be needed. So unless you know of specific apps (or just want to test) that need a specific kernel (2037?), I wouldn't bother. But KERNEL.SYS is really the only file to worry about (shell should be the same). In short, if you want to dual boot between FreeDOS versions, you're basically only worrying about the kernel. In that case, a simple "ren kernel.sys kernel2.sys" and "ren kernel3.sys kernel.sys" should do it (and reboot, of course). Would this be a good time (doubtful) to suggest "XCHG" as a mnemonic for swapping filenames? ;-) -- BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.

You can't dual-boot multiple FreeDOS instances on the same partition, because you can't configure the kernel to use one specific (FD)CONFIG.SYS. Therefore, you have to change the file name the kernel will look for. If you can compile the kernel yourself, search through its source code for where the FDCONFIG.SYS name is used and change that. If you have an uncompressed kernel binary, you might be able to change the "FDCONFIG.SYS" string with a hex editor instead. >> The autoexec.bat file is the only file I seem to be able to rename >> without issue. > > "COMMAND /P:blah.bat" is typically where you change that (in CONFIG.SYS).

MetaKern should probably do it, I hope, but you'll have to read the docs and experiment. Keep in mind that MS-DOS (and thus Win9x) expect to be first on the drive, and I mean literally like sector 0 has to have the DOS files.

Depends on your definition of 'installed' (on same partition). If you install FreeDOS 1.0 first to a directory and then 1.1 to another directory, you've got 2 different installations. The only issue are the bootfiles, as you're already experiencing. Kernel can have any valid 8.3 name you like, but bootsector and SYS expects KERNEL.SYS by default. If you have 2 kernels KERNEL10.SYS and KERNEL11.SYS you could swap for example by doing a: SYS C: C: /BOOTONLY /K KERNEL10.SYS followed by a reboot. > After editing the fdconfig.sys, and autoexec.bat, I was unable to boot > properly with the files renamed. The kernel seems to be the only non issue, > but I hadn't tested it a whole lot. Maybe some programs need it named > 'kernel.sys'? I don't think you can set the configuration file that the KERNEL expects (default is CONFIG.SYS , unless FDCONFIG.SYS exists, then that's used instead) through a SYS CONFIG directive. > If I rename command.com in the root directory, there are obvious issues. If > I rename fdconfig.sys, there are issues. The autoexec.bat file is the only > file I seem to be able to rename without issue. The trick is moving as many drivers outside of CONFIG.SYS and in AUTOEXEC.BAT instead. It appears you can move all drivers this way, but memory management will be severely impacted if no XMS driver (HIMEMX/XMGR/JEMMEX/FDXMS286) in config.sys loaded due to no DOS=HIGH, nor DOS=UMB, nor DOSDATA=UMB and every driver loading in conventional memory. FreeCOM and 4DOS are notorious as (primary) shells in that they consume at least 100KB of memory, without ability of afterwards swapping themselves to XMS should you happen to load an XMS driver sometime (JEMMEX LOAD ; DEVLOAD XMGR.SYS). HMA nor UMB will become available from commandline, though expanded memory can be conjured this way by JEMM/JEMMEX What you could do is modify (FD)CONFIG.SYS and duplicate the menu entries. Using the SHELL= line you can easily load COMMAND.COM from each FreeDOS installation, and same for a starting batchfile (like AUTOEXEC.BAT): 1?SHELL=C:\FDOS10\BIN\COMMAND.COM A:\FDOS10\FDAUTO.BAT 2?SHELL=C:\FDOS11\BIN\COMMAND.COM A:\FDOS11\FDAUTO.BAT > Does anyone else here have a method that would allow multiple installs of > FreeDOS (1.0, 1.1), MS-DOS, or Windows 95/98 to co-exist in the same > partition? Win9x can coexist with older MSDOS 6 just fine (using WINBOOT.SYS for Win9x system file then instead of IO.SYS or MSDOS.SYS as MSDOS6 has them in use) > BTW - If this is the wrong place to post these types of questions, could > someone point me in the right direction? It's fine, just expect to get technical feedback to technical questions. As such the freedos-devel list might be more suitable if people on this list dislike long mails :) My own preference would be to have 2 ISO files (of FD1.0 and FD1.1) and simply mount those at startup.
