|boot = /dev/hda
|vga = normal
|
|Sashto taka zapis za parvia Linux:
|

|
|I oshte edin zapis koito da sochi nachaloto na Mandrakeskia partition:

| read-only

Niama da stane taka. Az zatova pisah, che ne moze s prerazkaz po
kartinka da se opraviat takiva neshta. Sega v tova koeto predlagash
ima edin osnoven kusur. Zadal si samo edno
root = /dev/hda1

Spored men vtoria linux triabva da se zadade s oshte edno 
root = /dev/hda2

Ima znachenie kyde mu e MBR. Obache ne mozeme da znaeme kak i shto bez
da imame lilo.conf, koeto toi se opitva da modificira. Spored men
dobre si e
boot = /dev/hda

Poglezdame kakvo pishe v dokumentaciata za LILO: 

Per-image options for kernels
[del...]
ROOT=<root_device> Specifies the device that should be mounted as
root.  If the special name CURRENT is used, the root device is set to
the device on which the root file system is currently mounted. If the
root has been changed with  -r , the respective device is used. If the
variable ROOT is omitted, the root device setting contained in the
kernel image is used. It can be changed with the rdev program.                                                               

Ima si i primer:
image = /vmlinuz
        label = lin-hd
        root = /dev/hda2
image = /vmlinuz
        label = lin-fd
        root = /dev/fd0   

Situaciata e analogichna. 

Syshto taka niama mnogo goliama nuzda na dvata Linuxa da ima
instalirano Lilo. Edno stiga na edinia ot dvata. Tova koeto ti se
opitvash da napravish e ednoto lilo da da bootne drugoto. Sigurno moze
i da stane opbache v takyv sluchai konfiguraciata na Mandrake triabva
da ima drug vid.

boot = /dev/hda2
           ^^^^^^!!!!
vga = normal

image = /boot/zImage
 root = /dev/hda2
 label = Mandrake
 read-only

Eto, che izpisah suma neshta. I za k'vo triabvashe, kato beshe
dostatychno pitashtia da pusne negovite lilo.conf i togava sigurno
shtiahme da se razbereme na edin red.
