[syslinux] Memdisk and big floppy images

[R S]

The narod.ru images are super outdated (FreeDOS kernel 2028) unfortunately.

If you are interested I could provide a 5MB FDD image template based on
FreeDOS 2041 kernel (the latest available at that time in 2014) where you
would just inject your ROM and EXE (and possibly adjust autoexec.bat to
autostart/apply the FW update). It's a minimal FreeDOS FDD image that
defaults to a clean boot with bare minimum settings (selectable in
config.sys) and I used this template over several years for a variety of
server FW updates. (FreeDOS hasn't been much updated over the years,
however I just found that 2042 is now available on Github.)


Included files in my template FDD image:

WATCOMC compiled FreeDOS Kernel 2041 (2012-02-07) with FAT12, FAT16 and
FAT32 support.
8086+ (CMD8086.com) and 80386+ (COMMAND.com) CPU compatible (config.sys
selectable).

CMD8086.COM v0.84-pre XMS_SWAP (2006-06-06) and COMMAND.COM v0.84-pre2
XMS_SWAP (2006-08-28)
HiMemX v3.32 (2008-03-13) and Jemm386/JemmEx v5.75 (2011-05-31)
NANSI v4.0d (2007-05-26) for FreeDOS logo.

Config.sys looks like this:

MENU FreeDOS 2041 Config.sys Presets
MENU -------------------------------
MENU
MENU 0 -> CMD8086.COM / 8086+ / CleanBoot (BIOS and Firmware) ( No XMMs )
*MENU 1 -> COMMAND.COM <http://COMMAND.COM> / 80386+ / CleanBoot (BIOS and
Firmware) ( No XMMs )*
MENU 2 -> COMMAND.COM / 80386+ / HimemX ( XMSv3 )
MENU 3 -> COMMAND.COM / 80386+ / HimemX + Jemm386 ( XMSv3 + EMSv4 )
MENU 4 -> COMMAND.COM / 80386+ / JemmEx (HimemX/Jemm386 combo) ( XMSv3 +
EMSv4 )
MENU 5 -> COMMAND.COM / 80386+ / JemmEx Safe (NOHI NOVME etc.) ( XMSv3 +
EMSv4 )
MENUDEFAULT=*1,0*
