yes, this is about BIOS/Firmware updates
Have a look at current firmware version on the target machine
dmidecode -t system dmidecode -t bios
grab the latest although not maintained 10M disk snapshot
wget http://www.fdos.org/bootdisks/autogen/FDSTD10.zip unzip FDSTD10.zip rm -f FDSTD10.pln FDSTD10.vmdk losetup --find --partscan --show FDSTD10.IMG mount -o loop /dev/loop2p1 /mnt/ cp -f fw/* /mnt/ #v1.2 overwrite AUTOEXEC.BAT umount /mnt/
Fetch the latest FreeDOS floppy release as shown in PXE/DOS.
Get MS-SYS up and ready
wget http://prdownloads.sourceforge.net/ms-sys/ms-sys-2.6.0.tar.gz tar xzf ms-sys-2.6.0.tar.gz cd ms-sys-2.6.0/ make -j4 make install
Inspect the current situation
ms-sys ../msdos/dos622.img ms-sys ../msdos/win98sc.img ms-sys FLOPPY.img ms-sys FD12LITE.img ms-sys FD13FLOP.IMG
Get the FreeDOS tree ready
mkdir lala/ mount -o loop FLOPPY.img lala/ #mount -o loop ../msdos/win98sc.img lala/
and when all the hassling is over
umount lala/ rmdir lala/
Create a FAT16
MBR partition on the memstick, e.g. +100M
wide AND SET IT BOOTABLE
fdisk -c=dos /dev/sdc o n p 1 63 (62?!) +100M t 6 a w
Format it as FAT16,
partprobe /dev/sdc ll /dev/sdc* mkfs.fat -F16 /dev/sdc1
Copy the operating system onto it and eventually some needed ROM and flashing executables,
mount /dev/sdc1 /mnt/ cp -R lala/* /mnt/ #yes, there is a folder in there cp -f fw/* /mnt/ #v1.2 overwrite AUTOEXEC.BAT ll /mnt/ umount /mnt/
Write the boot-codes using MS-SYS
ms-sys -h ms-sys --write --force /dev/sdc ms-sys --fat16free /dev/sdc1
dd if=/dev/zero of=floppy288.img bs=1024 count=2880 mkfs.fat -F 12 floppy288.img ms-sys --fat12 --force floppy288.img mount -o loop floppy288.img /mnt/ cp lala/MSDOS.SYS /mnt/ cp lala/IO.SYS /mnt/ cp lala/COMMAND.COM /mnt/ #cp lala/CONFIG.SYS /mnt #cp lala/AUTOEXEC.BAT /mnt umount /mnt

dd if=/dev/zero of=fwstick12.img bs=1M count=10 mkfs.fat -F16 fwstick12.img mount fwstick12.img /mnt/ ms-sys --fat16free --force fwstick12.img

dd if=/dev/zero of=fwstick12.img bs=1M count=10 losetup --find --partscan --show fwstick12.img ll /dev/loop* mkfs.fat -F16 /dev/loop2p1 mount /dev/loop2p1 /mnt/ ... ms-sys --mbrdos --force /dev/loop2 ms-sys --fat16free --force /dev/loop2p1 losetup -d /dev/loop2
You can also grap the content out of the Lite version
wget http://www.freedos.org/download/download/FD12LITE.zip losetup --find --partscan --show FD12LITE.img ll /dev/loop* mount /dev/loop3p1 lala/ ... losetup -d /dev/loop3 umount lala/
