[ltp] updating bios on x60s: problem on image created

[Xavi de Blas]

Hello, i want to update my bios on my x60s and following this page:

http://www.thinkwiki.org/wiki/BIOS_Upgrade/X_Series

Seems the approach1 is the suitable for me (have external CD) and seems safe.

I used the script convertlenovo.sh but the image created is not
recognized at start
(reads the CD, but says: "not system disk. replace..."). Wondering if
i haven't burned ok the image,
i checked that bios from lenovo iso, and out.iso are quite big:

ls -l *.iso
-rw-r--r-- 1 xavier xavier  4608000 2008-11-04 12:13 7buj26uc.iso
-rw-r--r-- 1 xavier xavier 49905664 2008-11-04 13:30 out.iso

but if i mount out.iso:

sudo mount out.iso /mnt/usb_hdd/ -o loop

and i list contents:

ls -l /mnt/usb_hdd/
total 2
-r-xr-xr-x 1 root root 2048 2008-11-04 13:30 boot.cat

is only 2KB length !!

what i am doing wrong?

the shsucdrd.exe and shsucdx.com used are thiese:
