Thx... actually i am running an application on WinPE which is tesing RAM of the system. So i am allocating the memory using VirtualAlloc() API. My application runs finely when i run it on 256MB or above RAM but if i try to run this application on 100 MB ram, its getting failed. Any clue?

Hi All, When i boot my computer from CD having Win PE on it, can anybody tell me that how much RAM does it needs? or it runs from CD only ? Thanks !

hey, its wrking now.. anyways thanks for help

I want to test the total available memory in the system & thats why using VirtualAlloc, so how can a ram drive will help me in this? is there any other way to get the total available system meory & pointer yo starting location(smthing like INT15 h in DOS)

I think 1.2, its not mentioned specifically anywhere in the documentation i have

Hi, I am writing one application for Windows PE using vc++6.0 as development platform. I am allocating memory using virtualalloc as: VirtualAlloc (pPtrToMem, //NULL dwSize, MEM_COMMIT, PAGE_READWRITE); This is running fine on Win2k, but if I try to run this on Windows PE, i am getting an error as "paging file is too small to complete this operation(ERROR_COMMITMENT_LIMIT)" can anybody tell me how to increase pagefile limit in Windows PE? or is there any other reason? Any help is welcome. Thanks .

Hi, I want to find the address of extended BIOS memry address. This is done using INT 15/AX=0e820h in DOS(real mode) but I want this functinality in VC++(protected mode) which doesent support this function. even I tried writing device driver for executing kernel mode instruction but my system is crashing. So can any body help me with this. Thanks.

hi, i have tried using inline assemnbly, but vc++ compiler is not allowing key word int86x

Hi Spawn, thanks, but i tried to run one 16 bit DOS application(for serial port communication) on Bart PE with DOS plug in, but it diden't wrked, so i think none of the PE supports 16 bit DOS application(off course, it do support hello world!!) with system calls.

hi, i have a code having MSDOS functions such as int86x & segread written in microsoft c 6.0. now i want to port that code to 32 bit windows environment using vc++. but i am not able to find out APIs which eill wrk like int86x & also if anybody can tell me abt whether i can use inline assembly code for these functions ? it will be a gr8 hlp. thanks...

Hi Spawn, Ok, i was making misake u mentioned, tommorow i 'll add the code to winpesys.inf file. tanks, one more thing, how u got to read bartpe dos plug in cause i tried but cuden't , also, can u suggest me sm links where i can learn more abt plugins as now i am just adding code given by u thanks...

hi, its not wrking... what i did: 1>created .bat file with code given by u & put that in WINPE folder frm where u run mkimg or oscdimg file. isoroot i set to the folder in which i store my iso image. 2>Added the code in winpesys.inf file as followes: /*this part was already there in .inf file*/ [Version] Signature = "$Windows NT$" ClassGUID={00000000-0000-0000-0000-000000000000} /*added this*/ [DefaultInstall] AddReg = Setupreg.addreg /*here, added the code given by u*/ /*following is nxt part of winpesys.inf*/ [AddReg] ; ; MiniNT key ; HKLM,"ControlSet001\Control\MiniNT" . . . & then executed mkimg.cmd but wheni boot my PC frm tis CD & try to run DOS application , i get an error as "is not a valid win 32 application" whether i am missing smyhing or need to migrate my code?(code is written in microsoft c6.0 & uses int86x & REGS commands)

hi, for running oscdimg command, u need winpe environment & then u cretae image. so how do u ppl get that custom environment? currently i am using mkimg command first & then use the folder created by mkimg command as an input to oscdimg. is there any other way to do that? & also if i want to add my own exe, i add it to i386\system32 folder of custom winpe(created by using mkimg command) & then make image & burn it, it wrks fine but is there any other way to add ur own exe to winpe?

hi spwan, yeah, its confusing, can u elaborote it little more as i have never wrote scripts & played with registry?

hey, i am facing same problem, so whats the ans?
