Re: Without DVD-ROM, USB working... install it from the HD?

Hi,

Coming back to this, this might not be exactly the solution to this
one specific problem, but I still feel like I should mention it
somewhere!

FYI, GNU's GRUB 2.02 was just released. I don't know the full
changelog, but Phoronix says "better support for FreeDOS" (whatever
that means)! An earlier article says "improved FreeDOS direct loading
support"!

* http://www.gnu.org/software/grub/
* https://wiki.gentoo.org/wiki/GRUB2_Quick_Start

A quick search for "grub freedos" found some interesting links:

* https://wiki.archlinux.org/index.php/Flashing_BIOS_from_Linux
* https://wiki.gentoo.org/wiki/BIOS_Update
* https://wiki.gentoo.org/wiki/Bootable_DOS_USB_stick

...

"The mkpkg action will create the floppy image ... so that the user
can boot to the image from the hard drive to flash the BIOS, without
needing a floppy drive."

"The install action will create the biosdisk image, copy the image
file to /boot, and then update the bootloader with an entry for the
image. Then all the user has to do is boot the system and select the
image to flash the BIOS; this will load the biosdisk image directly
from the hard drive and flash the BIOS."

It also has a section called "Images that are too large for a floppy"
that grabs a 10 MB image from http://www.fdos.org/bootdisks/ . That
uses "mount -oloop" and says "The image can now be copied to a USB
stick for booting, or booted as a memdisk".

It also mentions genisoimage for adding 1.44 MB floppy image to .iso for CD/DVD.

Or use the floppy image (as initrd) with GRUB via SysLinux's memdisk
(as kernel).

If needed, there's also geteltorito.pl that will extract .img from
.iso, which can then be copied to "USB thumbdrive".

...

The Gentoo wiki mentions fdboot.img and sys-freedos-linux. They create
a 20 MB image (via dd) and mkfs.fat, sys-freedos.pl on it, mount -o
loop, then copy files, etc.

"Booting the FreeDOS image from GRUB directly"

"To boot FreeDOS without any external media use the memdisk tool from
syslinux to allow grub (or another bootloader) to boot the FreeDOS
image directly." (Basically copy memdisk and freedos.img to /boot and
adjust grub.conf accordingly.)

...

The Bootable DOS USB (Gentoo) page is also interesting:

They mention using dd, cfdisk, ms-sys, mkfs.fat. They also use DOSEMU
(sys and xcopy) and test the raw USB device itself in QEMU.

...

So, in short, it's still overly complicated, but there are ways of doing it.
