The other message still appears i= f=20 the load address is high enough. This is how I'm testing: I've downloaded the August (20040813) version of wine applied the patch to= =20 comment out the reservation of the dos area in a previous email (attached=20 again, idealy we shouldn't apply this since having the stock wine work woul= d=20 be much better), and did a ./configure && gmake depend && gmake && gmake=20 install. I've attached my wine config file. Then I just end the=20 environmental variable you said and run wine. I'm using Diablo 2 as my tes= t=20 app. =2D-=20 Anish Mistry --Boundary-02=_/sIRBctZakl5Vdz Content-Type: application/pgp-signature Content-Description: signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQBBRIs/xqA5ziudZT0RAkpCAKCVw5V8CHO2fVgm46C+j90N/YRtUQCfU7KU RzQn/aUUMWBjP3mjWgkKn9s= =PWX+ -----END PGP SIGNATURE----- --Boundary-02=_/sIRBctZakl5Vdz-- --Boundary-00=_+sIRBuYt87PX2OZ Content-Type: text/x-diff; charset="iso-8859-1"; name="wine-mmap.patch" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="wine-mmap.patch" --- libs/wine/mmap.c.orig Mon Sep 6 01:23:40 2004 +++ libs/wine/mmap.c Mon Sep 6 01:23:46 2004 @@ -294,7 +294,7 @@ area = LIST_ENTRY( ptr, struct reserved_area, entry ); if (!area->base) return; } - reserve_dos_area(); + /*reserve_dos_area();*/ } #else /* HAVE_MMAP */ --Boundary-00=_+sIRBuYt87PX2OZ--
