My OS are installed as follows:

Windows 7 on /dev/sda1 (primary) type=7 (HPFS/NTFS)
WinXP on /dev/sda2 (primary) type=c (W95 FAT32 (LBA))
Linux on /dev/sda6 (logica1)

I'd like to make Win7 hidden (and deactivated)
when booting WinXP from lilo (and conversely).
Following the lilo manpage I set up the boot items

# Windows bootable partition config begins
other = /dev/sda1
label = Win7
table = /dev/sda
change
automatic
partition=/dev/sda1
set=["NTFS"]_normal
activate
partition=/dev/sda2 <== Line 50
set=["FAT32_lba"]_hidden
deactivate
# Windows bootable partition config ends
# Windows bootable partition config begins
other = /dev/sda2
label = WinXP
table = /dev/sda
change
automatic
partition=/dev/sda1
set=["NTFS"]_hidden
deactivate
partition=/dev/sda2
set=["FAT32_lba"]_normal
activate
# Windows bootable partition config ends

(I wasn't quite sure of the syntax of the set line)
Anyway, lilo returns an error:

root@Oscar:/etc# lilo
Warning: LBA32 addressing assumed
Added Linux *
Unrecognized type name at or above line 50 in file '/etc/lilo.conf'

Line 50 is indicated above. I have experimented with variations
on the above, but still can't get lilo to accept my syntax.

Any comments?

Got it (I think)

Note changes from above:

# Windows bootable partition config begins
other = /dev/sda1
label = Win7
table = /dev/sda
change
# automatic
partition=/dev/sda1
set=NTFS_normal
activate
partition=/dev/sda2
set=FAT32_lba_hidden
deactivate
# Windows bootable partition config ends
# Windows bootable partition config begins
other = /dev/sda2
label = WinXP
table = /dev/sda
change
# automatic
partition=/dev/sda1
set=NTFS_hidden
deactivate
partition=/dev/sda2
set=FAT32_lba_normal
activate
# Windows bootable partition config ends

(note "automatic" is cancelled) and then

root@Oscar:/etc# lilo
Warning: LBA32 addressing assumed
Added Linux *
Added Win7
Added WinXP
Added Linux.old
One warning was issued.

The syntax for the set entries can be found by typing

root@Oscar:/etc# lilo -T ChRul
