USB booting :: New Updated Install to Pendrive



Windows XP sees only the first partition so there's no point making a large second FAT partition.

I increased the size of the 50MB FAT partition to the maximum 250MB (with USBZIP method) which is now accessible from Win. The rest of the stick is ext2 for dsl extensions and the backup file.

I'd love your script fo./mkdiskimage -1 /dev/$DEVICE 50 64 32
r a 256mb partition...  
In you script, I noticed the "./mkdiskimage -1 /dev/$DEVICE 50 64 32" seems to make the geometry... I take it this line would have to be modified for different geometry right?

This worked for me. It was exactly what I was looking for.

Now I have a 512MB stick w 2 partitions of ~ 255 of which the first has 200 left as windows compatible FAT.

thx for helping me out, haven't seen any perl scripting (mkdiskimage) before, drove me crazy.

I believe this is only an XP limitation.
W2K, ME, 98, 95, etc.. all can see more than one partition..

I have also adjusted the FIRST number in the mkdiskimage
command, from 50 to 200, which still makes a bootable
partition on sda1..  It seems , that using the "zip" technology
only allows a maximum of 256MB's for booting from the first
partition. ( something about making the blocks to big )

put simply, the hardware and software guys
at qnx RTP seem to have at least a partial answer
(dont worry RTP works very much like *Nix).

it may be related to some problems with the geometry of the usb-flash
http://www.openqnx.com/PNphpBB2-viewtopic-t2882-.html

fmartens seems to give links to some tools that may help
to reset/format the geometry right ?.

RTP is a VERY cool OS and free to home users/open devs.

Mike, try running from a shell. Maybe the script has error'ed out on you.
From  the shell prompt

$ dsl-usbinstall

I probably should edit in a bunch of pauses in the script. But you see I always do all of my installs from runlevel 2. But if you run from shell you should not have any quickly disappearing messages.

As to the other question. During testing it was discovered that the auto geometry begins to fail with anything higher than 256MB. So, in order to try to accomodate all sizes of pendrives, it was decided to make a small 50MB fat and the remaining linux. This seemed to work on all the pendrive that were field tested.  I still have my original script that works up to 256MB and makes a single fat partition.

can i installl to kingston 128 mb?? how ???
