  Build process
================================================================================

	make kernelconfig
	-> and configure kernel for example with kernelconfig.example options
	make kernel

	At this point, microkernel is built

	make bootstrap
	make bootstrap-install

	Now, you have built bootstrap code (multiboot info code and required
	sigma0).

	make freevms

	All FreeVMS kernel parts are build. If you have a image disk mounted in
	../mnt, you can install all files with:

	make image

================================================================================
  Build image
================================================================================

	FreeVMS requires a partitionned disk image and a modified grub that
	handle ODS2, EXT2 and multiboot information. To build a disk image,
	run the following instructions:

	Initialize an empty disk image with dd (for example a 80 MB hard disk)

Root cauchy:[/home/bertrand/openvms] > qemu-img create -f raw image.img 80M
Formatting 'image.img', fmt=raw size=83886080
Root cauchy:[/home/bertrand/openvms] > sfdisk -D image.img << EOF
> ,,L,*

Warning: image.img is not a block device

Successfully wrote the new partition table

Re-reading the partition table ...
BLKRRPART: Ioctl() inappropré pour un périphérique

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)
Root cauchy:[/home/bertrand/openvms] > 

	Now, we're going to mount this disk image.

Root cauchy:[/home/bertrand/openvms] > fdisk -l image.img
You must set cylinders.
You can do this from the extra functions menu.

Disk image.img: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x62e92de4

    Device Boot      Start         End      Blocks   Id  System
image.img1   *           1          10       80293+  83  Linux
Root cauchy:[/home/bertrand/openvms] > 

	First partition begin at 1*63*512 (start cylinder * sector per track *
sector size).

Root cauchy:[/home/bertrand/openvms] > losetup -o $((63*512)) /dev/loop0 \
		image.img
Root cauchy:[/home/bertrand/openvms] > mkfs.ext2 /dev/loop0
Root cauchy:[/home/bertrand/openvms] > mount /dev/loop0 mnt
Root cauchy:[/home/bertrand/openvms] > losetup /dev/loop1 image.img

	Now, you only have to install grub2 on boot record. Grub2 is built
into build/bootloader.

Root riemann:[/home/bertrand/openvms/FreeVMS/build/bootloader/build/sbin] >
./grub-install --boot-directory=/home/bertrand/openvms/mnt --target i386-pc
--modules=part_msdos /dev/loop1

	That's all, folks !
