In direct emails with I believe this user, or at least someone with same system the above newer version of the program was able to see the hardware. It has newer kernels, busybox, and syslinux. Not sure why the earlier version would see the /dev/sdb in the /proc/partitions, but not via fdisk.
If this is not the same user, please try the above version, and see if it works for you.
The last email I got had the follow reply.
I tried the version you advised me both 25.9 and the latest version, and everything works.
The disks are all detected and available.
Also my network card was also detected which came to a big surprise for me.
The only thing it was missing was a dhcp configuration for the card out of the box.
But everything else was perfect.
Thanks for everything.
If you need something from this version just tell me and i'll send it to you.
The notebook i'm working on is a sony vaio SZ71XN just as information for future debug
