Next, I installed Windows-95 on my office system. It blew away my nice Lilo MBR, but it left my Linux partitions alone. Kernels take a long time to load from floppy, so I made a floppy with a working Lilo setup on it, which could boot my kernel from the IDE.
I made the lilo floppy like so:
fdformat /dev/fd0H1440 # lay tracks on virgin diskette mkfs -t minix /dev/fd0 1440 # make file system of type minix mount /dev/fd0 /mnt # mount in the standard tmp mount point cp -p /boot/chain.b /mnt # copy the chain loader over lilo -C /etc/lilo.flop # install Lilo and the map on the diskette. umount /mnt
Notice that the diskette must be mounted when you run the installer so that Lilo can write its map file properly.
This file is /etc/lilo.flop. It's almost the same as the last one:
# Makes a floppy that can boot kernels from HD. boot = /dev/fd0 map = /mnt/lilo-map delay = 100 ramdisk = 0 timeout = 100 prompt disk = /dev/hda # 1 GB IDE, BIOS only sees first 500 MB. bios=0x80 sectors = 63 heads = 16 cylinders = 2100 image = /vmlinuz append = "hd=2100,16,63" root = /dev/hda2 label = linux read-only vga = extended other = /dev/hda1 label = msdos table = /dev/hda loader = /mnt/chain.b
Finally, I needed MS-DOS 6.2 on my office system, but I didn't want to touch the first drive. I added a SCSI controller and drive, made an msdos file system on it with Linux' mkdosfs, and Windows-95 sees it as "D:". But of course MSDOS will not boot off of D:. This is not a problem when you have Lilo. I added the following to the lilo.conf in Example 2.
other = /dev/sda1 label = d6.2 table = /dev/sda loader = /boot/any_d.b
With this modification MSDOS-6.2 runs, and it thinks it is on C: and Windows-95 is on D:.
