while booting Moblin Linux from the PATA Hard disk. The Moblin Linux installation on PATA HDD is successful, but after installation, it requires USB-live image support to initially boot and then transfer the control to PATA HDD through boot select menu. Listed below are the steps which were performed
a. The Platform has USB drive (having a live image as primary boot
device) as boot partition and PATA as secondary disk.
b. The system is booted from the USB drive
c. From Moblin boot image menu, boot (default) option is selected.
d. Booted the platform with live image
e. Installed the live image to the PATA HDD through the Moblin
installer utility
f. The PATA HDD contents were checked by mounting the drive.
g. The grub configuration was changed to boot it in echo mode
h. In the grub configuration we added rootwait and root_delay=5
i. Then we rebooted the system with USB drive (having a live image)
as primary boot device
j. As it reaches up to boot menu, the USB drive was removed and "Boot
from Local Disk" option is selected. This was done to ensure that the
system boots from the HDD (as it is the only medium available).
k. The system booted up fine.
l. Verification is done by checking the mount points, in case of PATA
HDD the mount points are:
i. /dev/sda1 /boot
ii. /dev/sda2 /
When the system is rebooted again without the USB drive it boots till
the Kernel selection page, but after that it hangs there.
Digging the image isolinux configuration, we found that "Boot from local
disk" option does the following -
localboot 0xffff , i.e. it raises a INT18
interrupt to boot from the next device.
Our understanding is installation might not be able to find a bootable
partition, but trying to make the /dev/sda1 partition bootable results
in an error -
"Syslinux: unable to find any valid fat file system on /dev/sda1"
Any suggestion or pointers to resolve this issue will be of great help.
