Limit of ROM

[SheikhAatif]

What is the limit of the ROM in XDA Atom?

I have placed a content of about 205 MB in SYS& OEM Folder. Now I want to Cook the ROM? Will it work or there should be any limit in this folder?

Sheikh Sahib yes there is a limit, as a thumb rule remember 30 MB in OEM and 65 MB in Sys folder are generally good to go at least in Atom Exec. But Atom and Atom Exec are almost the same except that Atom Exec has a faster processor and more RAM.

:( But when I dumped many ROM from PDAVIET, I saw that "dump" Folder was 132 MB, 164 MB, 110 MB etc....



:confused: Upto How much MB can I add to the folder?
and If I add upto 210 MB? Will the ROM get installed on My XDA Atom?

1. OK let me explain in simple words, if u check "diskimage_Ver.nb0" size it is 64001 KB now tell me can I put a bigger then this size of file?????
Well not, but once u build a ROM there is some compression used and the files in OEM and SYS folders get compressed and filled in the "diskimage_Ver.nb0".

2. Now coming to decompressing or dumping a ROM u get a lot more cause' all of the dll (folders) when dumped through "BuildOS.exe" have a file dll inside also. For example after dumping a ROM check the "commctrl.dll" in OS folder of ur Sys and u will see that inside this "commctrl.dll" u have a imageinfo.bin file alongwith a number of S000, S001.... files and a commctrl.dll file. Now u do not need this dll file inside the folder dll, that is even if u remove this u will get a bootable system. To clarify it further the "BuildOS.exe"removes these files automatically. To sum it all u have about 400-500 duplicate dll's and if u remove them u will get atleast 40-50 MB less size :).

Was that easy or did I confuse u even further :confused:.

I don't think so, you must replace the driver and xip to make it work.
