WOW32/Win16: Applications not having enough memory #107

Closed isaacmakessoftware closed 2 years ago

isaacmakessoftware commented 3 years ago

I am looking for a way to increase the allocated memory for the win16 applications. They perform slow and often ask for more extended memory or changing my system config with more ram. This is not an issue and on 32 bit windows does not happen. Is there a way to increase the ram allocated for win16 applications? DOS apps work fine, even faster than DOSBOX, but win16 needs more ram.

leecher1337 commented 3 years ago

Thanks for testing WOW16 support. Hm, normally, NTVDM takes memory settings from an accompanied .pif file. But this mainly applies to DOS applications, I think. Do you have a sample for a publically available Win16 application that asks for more RAM, so that I have a test case to check?

Performance- and compatibilitywise, you may be better off with winevdm yet (you can use it additionally to NTVDMx64, they don't interfere with each other). Maybe I get HAXM build to also work with WOW16 some day for better hardware-accellerated performance, currently NTVDMx64 HAXM build only works for DOS applications.

Hey leecher1337 thanks for the info. I am using a copy of lotus smartsuite 4 from winworld https://winworldpc.com/product/lotus-smartsuite/40 It is very slow and says "not enough RAM available to continue". The WINEVDM is ...................... well wine and does not work as well as your solution. Hope that helps, maybe there is a config file I can edit to increase the ram.

isaacmakessoftware commented 3 years ago

It's a very slow install process, it took me 2 hours. It keeps giving memory errors and not opening applications, and the file copy is slow probably cause of the ram.

isaacmakessoftware commented 3 years ago

Ok I'll test updated version of the application Thanks for the effort, it must not be easy I am also sorry I didn't reply earlier, I got a bit busy

Short update on the meory issue that seems to be plaguing Lotus Smartsuite: It doesn't seem that the VM doesn't have enough mem. It seems that the TOOLHELP.DLL library, which is used to call SYSTEMHEAPINFO function just thinks that it's not initialized and therefore fails the call:

If you look at the code of SystemHeapInfo in WOW16, you see:

    if (!wLibInstalled || !lpSysHeap ||
        lpSysHeap->dwSize != sizeof (SYSHEAPINFO))
        return FALSE;

wLibInstalled is a global that gets initialized on TOOLHELP init:

    /* Unless we say otherwise, the library is installed OK */
    wLibInstalled = TRUE;

    /* Do the KERNEL type-checking.  Puts the results in global variables */
    KernelType();

    /* If the KERNEL check failed (not in PMODE) return that the library did
     *  not correctly install but allow the load anyway.
     */
    if (!wTHFlags)
    {
        wLibInstalled = FALSE;

        /* Return success anyway, just fails all API calls */
        return 1;
    }

So I somehow have to find the code path where toolhelp loads and check why it fails. Unfortunately, it's a PITA to debug Win16 apps. I can do instruction tracing with Yoda, but it doesn't resolve any symbols, thus I have to match it with disassembled Win16 binary in order to find the execution flow.

leecher1337 commented 3 years ago

Seems to be a problem with the columbia.edu build, if you build it yourself, you get a slightly smaller toolhelp.dll which doesn't exhibit the problem. As you said you are trying to build the latest release yourself anyway, can you verify that the memory error is gone with it too?

isaacmakessoftware commented 3 years ago

Hmmmm.......I am still trying to figure out how to build it but when I do I will update you

leecher1337 commented 3 years ago

Just use minnt build instructions. But I found out that I locally built toolhelp from newer source than NT4 source (whereas build process uses classic NT4 source), that explains the difference. I need to issue a patch then, but at least I found the reason and know how to fix it, will issue a commit soon.

isaacmakessoftware commented 3 years ago

I don't know if you still remember me but I finally managed to build it with the needed requisities (your youtube video was helpful). However, I am getting file errors when it asks if I want to install the WOW32 support. It can't find miscellaneous files, and when checking, they indeed were not there. The columbia.edu build contained those files, so what is the problem?

leecher1337 commented 3 years ago

Hi, which files are missing? If you had an error with building them, you should see errors in buildchk.err file.

isaacmakessoftware commented 3 years ago

I'll check and update you.

isaacmakessoftware commented 3 years ago

Quite a couple files are missing, see the screenshots uploaded. The one with the fewer files is the build I did, the one with more is the columbia.edu build. Buildchk.err contains two awkwardly placed text lines that go as follows: 1>NMAKE : fatal error U1077: 'exe2bin' : return code '0x1'

1>NMAKE : fatal error U1077: 'exe2bin' : return code '0x1' What could that mean? 2020-12-19_15h05_09 2020-12-19_15h05_47

leecher1337 commented 3 years ago

exe2bin error could be due to https://github.com/leecher1337/ntvdmx64/issues/82#issuecomment-607463113

leecher1337 commented 2 years ago

No further information given on exe2bin issue, assuming solved by deletion of exe2bin.exe in System32 directory
