Question...
I have 128MB RAM in my US T-Mobile with the driver for using the upper 64M. If I had the guys at T2T swap my 32MB ROM for a 48MB ROM similar to what the older Ipaq's were using, could I use all of it with the kitchen? Would it be accessible by the OS?
I'd like to squeeze Fonix and Pocket Informant into ROM and there's just not enough room today.
Just a thought...

Hi,
I cant answer that question but could I ask you one?
Whats the driver to use the upper 64mb for RAM?
thanks.

I've just spoken with the folks at PPCTechs and they do not offer ROM memory updrades.

right........
... trys to siphon the information from him telepathically
Nope? I think you?ll have to tell me ;)

The guys at http://www.pocketpctechs.com/ make a driver for it. They only sell it with the purchase of the memory upgrade and service.

Ok, let's say I have a soldering iron and an old Ipaq that I could steal the ROM from and put in the HTC. Any idea if we could use the extra memory for stuffing applications in using the kitchen :?:

Ok, first off, have you seen the inside of your XDA?
Second, unless you are good with multi-layered pc-boards and do not get anything else on and in the board hot, than you may (note may) be able to pull off the chip swap. Mind you not damaging any of the shileding and compromising the frequincy levels.
Third, are you really sure you want to risk your XDA by soldering ROMs that may not be compatible with the circuit in the XDA?

The point isn't if I can get the 48 MB ROM in the device :roll: , my question is specifically can I use it if I do? If we tweaked a kitchen to go above the 32MB current limit, will the XDA have any issues reading the additional ROM :?:

Read my above reply very carefully. It is very specific on the even if you could get it in the device that it may not work with the circutry in the XDA. Most manufacturers use ROMS in a device like this that are specific in capibilities and than design the rest of the circut around that. Now this doesn't mean the chips won't line up pin for pin, but even if they do you have to make sure the internal functions of those chips match the same pin configuration as the previous chips pin configuration. As in you may have 48mb ROM chips that have a Positive Power feed where it needs a ground for the XDA's Circuit. This plugging the chip in means dead both. Even if it is a match, the XDA may be limited to seeing only 32mb ROM as a physical barrier and anything more will produce an error in the unit.
IF you do more research in electrical design you can find this out and I DO recommend it than you can analyze the circut yourself and determine if it can handle it or not. Also, you need to "Cold" solder the chips. A soldering iron will destroy the board. At the least damage it as it was designed heat sinsitive.
