UNHIDE the EXT-ROM in DCD's 3.01 kitchen

If it could be turned into a swapfile or a second pagepool, that would be ideal.

I am familiar with swap files and virtual ram on the PC. And I do remember your post before on this. I actually tried to get it to work. I'm the silent type I guess. But, I do see where you are going with this as this will be a huge breakthrough in my eyes. Considering, one of the major flaws to me about the Mogul is the ram. If you are successful in your attemps, this my friend will put he Mogul up a couple of notches. And with No2Chem's ExtUnlock I was very unsuccessful and I didn't want to try what was on XDA Developers site. Cause they haven't figured out the double ext rom in file explorer. I don't know. I tried everything and I just wish you well on your discoveries to help ease a little headache of mine. Good Luck.

bunvilla, any new info? I would really like to unhide the ExtROM when cooking my next ROM (which may be soon)

I was just thinking, not even sure if it's possible, but if we did have an extra 10MB or so to work with that looked like a mounted volume, wouldn't it be cool to somehow move filesys.exe and devices.exe over to that partition. Like I said, I'm not real familiar with these two executables, but that would free up at lease 8MB of program memory for the Titan.

Main problem with that would be 3 things...
1. Flash is ALOT slower than RAM. Writing and reading variables from it will grind even a simple application to a halt.

2. Flash has limited read/write cycles before it breaks down. Although its a lot (I believe several 100,000 cycles), using flash as virtual memory will severely reduce it's lifespan.

3. In order to accomplish this (in a reasonable amount of time) we would need source code for Windows CE's memory allocation code. And even then we would need to develop a algorithm to keep the most frequently used/speed vital information off the virtual memory.

In short, I don't believe this is feasible or even helpful as the speed would be awful.

Good post. I forgot about the differences between flash ROM and RAM.

Uhm guys, I looking more at increasing the pagepool C im thinking outside the box, there is no hard drive (like in a pc, spinning disks) So the chances are that the entire system (be it the memory that acts like a hard drive, or the memory that acts as system ram, or the memory that acts like a page pool, or the memory that acts the extended rom) it appears is all made up of 1 type of memory, possibly 2 and no more. So what it appears is that if u get the values right u can edit the reg to trick the WM6 into thinking the extrom is something else other than a extended partition. Having it show up as a REMOVABLE Drive on my phone proves that the memory can be manipulated and conventional wisdom must take a back seat, Speed of the memory is less important than the proper allocation of it, Virtual Memory or known as windows swap file takes hard drive space and uses it in a way that windows thinks its system memory, and the last thing in the world virtual memory is, Is system memory. But the computer thinks it is, u get it. the only way we will be able to figure it out is to think out side the box. so i have been lucky to make some progress cause i was about to give up, but i have a tuff road ahead in trying to solve this issue. never say never and wish me luck

You're not understanding. We all get that you want to increase the pagepool size and that's good, but "tricking" the OS into thinking that the extended ROM partition is really pagepool RAM might not be worth the effort. There's no way to "trick" the flashROM into making it as fast as RAM.
