ntloader in lilo...booting from secondary drive

icyfire · 07-10-2002, 05:41 PM

Hello All,

It's been a while since I've been here...

I obtained yet another harddrive for my computer; this makes 3x60GB. I have a RAID controller on my mobo, which gives me the extra 2 IDE channels I need, though I don't use RAID.

I have 3 hard drives...hde, hdf, and hdg. hde is on primary master, hdf is primary slave, and hdg is secondary master.

I installed linux to hde (obviously because it is the most important), and windows to hdg. (hdf is just data). On hdg there is a 110 mb partition for DOS and ntloader. Ntloader runs excellent when i switch the drive to primary master, but when i switch it back to secondary master, lilo runs and doesn't know how to boot from hdg.

Is this possible? If so, what lines do I need to add to lilo to have it boot ntloader when 'DOS' is selected??

Thanks,
icy

well i did leave out a tidbit of information:

i DID try it already, and i DID read the HOW-TO....

i tried the following lines in lilo:

other=/dev/hdg1
label=dos
table=/dev/hdg

i even tried taking away the last line, but that did nothing. when lilo runs and i choose dos, it says "loading dos" and then stops.

can anyone help? thanks a lot!

Maybe remapping the drives will work. Like this:

other=/dev/hdg1
label=dos
table=/dev/hdg
map-drive=0x80
to=0x81
map-drive=0x81
to=0x80

Then run /sbin/lilo. If it doesn't work, try changing the 0x81 to 0x82.

i tried that again.

actually that was what mandrake put in there automatically and it didnt work.

im very puzzled. i do NOT want to switch the order of my drives because that means taking my computer completely apart. its not as easy as it sounds. the thing weighs 40 lbs....need i say more?

Are you sure that hdg1 is the correct partition? What does fdisk -l /dev/hdg list as the partitions on hdg?

<Edit> Maybe changing hdg1 to hdg in the "other=" line will get it to work.</Edit>

tried that too....heres my fdisk -l output:

Code:

Disk /dev/hdg: 255 heads, 63 sectors, 7473 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hdg1   *         1        14    112423+   6  FAT16
/dev/hdg2            15       536   4192965    7  HPFS/NTFS
/dev/hdg3           537      7473  55721452+   f  Win95 Ext'd (LBA)
/dev/hdg5           537      1939  11269566    b  Win95 FAT32

Hey why not give you my lilo.conf too?

Code:

boot=/dev/hde
map=/boot/map
install=/boot/boot.b
default=linux
keytable=/boot/us.klt
lba32
prompt
timeout=50
disk=/dev/hde bios=0x80
message=/boot/message
menu-scheme=wb:bw:wb:bw
image=/boot/vmlinuz
     label=linux
     root=/dev/hde1
     append=" hdb=ide-scsi devfs=mount quiet"
     vga=788
     read-only
image=/boot/vmlinuz
     label=linux-nonfb
     root=/dev/hde1
     append=" hdb=ide-scsi devfs=mount"
     read-only
image=/boot/vmlinuz
     label=failsafe
     root=/dev/hde1
     append=" hdb=ide-scsi devfs=mount failsafe"
     read-only
other=/dev/hdg1
     label=dos
     table=/dev/hdg
other=/dev/fd0
     label=floppy
     unsafe

see if that helps. thanks again linuxcool, or anyone else who might know.

Ok. I see that you have this line:

disk=/dev/hde bios=0x80

This tells which bios number to associate with which drive. Let's add this line under it:

disk=/dev/hdg bios=0x82

Then try this:

other=/dev/hdg1
label=dos
table=/dev/hdg
map-drive=0x80
to=0x82
map-drive=0x82
to=0x80

If that doesn't work, change hdg1 to hdg.

Don't forget to run /sbin/lilo after each change. Good luck.
