So to round off this weeks technical series on the Pidion BM170 we’re taking a good look at the ULDR Menu. I guess some people would call this the “boot” menu or Boot Loader but essentially it’s a small hidden menu where you can do a few things with any Pidion device that can be really useful. This blog is good to go for all Pidions, so if you have a BIP-1300, 5000, 6000, or 7000 or even the older BM150R this is all good stuff for you too!
One word of warning before we delve in to this. Fiddling in the ULDR menu can seriously damage a Rugged PDA, I mean actual hardware damage can be if you don;t know what you’re doing so whilst this blog will show you what you can do with it, you must consult with your reseller before doing anything. We are happy to help too so just ask if you want some help.
Getting into the ULDR Menu
First we have to get the ULDR menu up. You do this easily by performing a hard reset but this time instead of pressing the “OK” key you hold down the “Send” key for 5-10 seconds. Instead of resetting or reloading the OS on the device, you’ll quickly see a DOS style menu pop up like the one below.
What do the 5 sections do?
There are 5 menu items and we’ll talk about what each does here:
1. Download Image
You won’t really use this at all. It allows you to download an OS image using various techniques. However the best way to do this is to use the SD card method found in (5) below.
2. Delete Hive Registry
This does exactly what it says on the can, I can’t say I personally remember using this feature before. It can screw your device up though if you’re not careful!
3. Format FlashDisk
This feature will format your FlashDisk or ProgramStore area. It will basically delete and format the whole area. If you do this and then try to hard reset the device, it will still reset but you may be missing some essential patches and startup files. This is good though if you really want to lock your device down and hard wire them to your own applications.
4. Nand Format and repartition
Now this is a useful feature because it allows you to fiddle with the Rugged PDA’s memory. from here you can alter the ProgramStores size from the default setting of 55MB. This is really useful if your apps are large and you want to try to cram everything into the persistent storage area of the device. You can also reduce the size to if you just want to use the device in a more generic smartphone manner. This will increase the ROM you have in the device.
Be warned that when doing this you will wipe the device totally and you will need to reload the OS again (See 5 below).
5. Image Reload
This allows you to re-image a device with a new OS. We can’t give out OS images willy-nilly so its a feature we use here rather than the end users for licensing reasons, however you can re-image your device from here if you have the right OS and boot files.
We do get asked what the ULDR menu does a lot here, and whilst it is a useful tool, this blog is really to show you what can be done, rather than what you should be doing yourself so always consult with your reseller before attempting anything in this article.
