I wasn't able to boot windows from lilo. Then I saw that someone had suggested to add "boot-as = 0x80" to the lilo.conf in the windows section.

I did that and now am able to boot windows from lilo.

I was wondering what does it do?

Thanks.

Hi

I think this reverses the disks

like let disk 1 be equal to disk 2
and disk 2 be equal to disk 1

It comes down from the boot order of the bios of the machine.

Not sure though will wait for other replies.

From the lilo.conf man page:

boot-as=<bios>
This option (LILO version 22.5.1) indicates the BIOS device code which must be
assigned to the specified drive in order for the "other=" operating system to
boot. If the chain loader detects that another BIOS device code is assigned to
this disk, then it will dynamically swap the assigned device code with the speci-
fied device code.

This option is easier to specify than "map-drive=" and more general than "master-
boot" in that any device code may be specified. Unlike "map-drive=", the determi-
nation whether to swap device codes is made at boot time, not install time. This
is advantageous on systems where the BIOS presents a boot menu of devices, and
will map disks to devices in different ways, depending upon the BIOS boot selec-
tion.

This option may by specified as a global option, in which case it applies to all
"other=" sections unless overridden with a specific "master-boot" option. If one
of "boot-as=" or "master-boot" is specified as a global option, it is better to
specify "master-boot" as the global option, as it will not interfere with floppy
disk BIOS device codes; "boot-as=" is then used as a local option to override
"master-boot" as necessary.

FYI, i use it for my dual boot of slack and windows and it works.

Windows can boot only from the 1st disk, so you may have to use that command to swap the disk numbers if you have more than one.
