Hi all,

i am trying to install GRUB to my compact flash. but i have some problem.

i am following these instruction:
http://julian.coccia.com/blog/index.php?m=200309&more=1
but i even fail in the first step

so i have grub 0.97 on my laptop.

Code:

#grub --version
grub (GNU GRUB 0.97)

the this is my partition:

Code:

#fdisk -l
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        4629    37182411    7  HPFS/NTFS
/dev/sda2            4630        9729    40965750    f  W95 Ext'd (LBA)
/dev/sda5            4630        5904    10241406    7  HPFS/NTFS
/dev/sda6            5905        6096     1542208+  82  Linux swap / Solaris
/dev/sda7            6097        7246     9237343+  83  Linux
/dev/sda8            7247        9729    19944666   83  Linux

Disk /dev/sdb: 523 MB, 523321344 bytes
255 heads, 63 sectors/track, 63 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1          62      497983+  83  Linux

it can be seen that my CF car is at /dev/sdb1
so the frist question is, i should install GRUB to /dev/sdb1 instead of /dev/sdb right?

then i read the

Code:

#info grub

about the naming convention. so for my CF it should be hd1,0 -> refering to /dev/sdb1 (first partition of 2nd IDE drive)

but why in the grub console, it is not recognized:

Code:

grub> root (hd1,0)

Error 21: Selected disk does not exist

any idea to install GRUB on the CF?

thanks

halo,

problem solved, someone helped me.

i have to add this line on my /boot/grub/device.map file:

Code:

(hd1) /dev/sdb1

then copy the following files to my the rootfs of CF at the same directory:

Code:

/boot/grub/stage1
/boot/grub/stage2
/boot/grub/reiserfs_stage1_5 (depending the filesystem will be used - maybe more than this one)

execute grub in su privilege

Code:

grub> root (hd1,0)
grub> setup(hd1)

grub installed, put the CF to target, reboot.
hope this helps someone

thanks
