hello once again guys... need help with my dilema... heres my setup which i was able to run using two os (xp/me)... rldelrosario ======== OS: Windows ME Memory: 2 GiB RAM (2x 1 GiB) Motherboard: P4X333-8235 CPU: Intel P4 2.0GHz Video card: nVidia GeForce FX5500 256 MB (AGP 4x) config.sys and autoexec.bat: no relevant entries system.ini: MaxPhysPage=48000 ; 1150 MiB MaxFileCache=131072 ; 128 MiB vmm32.vxd: plain vanilla (with 4.90.0.3000 vcache.vxd and vmm.vxd inside) i was to run the two OS by editing the sys.ini using windows xp before... my problem now is that my harddisk crashed and after having it checked, its a goner, so i had to get a new one and have new installs. thing is... before, i was able to install the two os (xp/me) by first installing ME, then upgrade it to xp. and then reinstall ME using (windows.000) folder. but the installs were made before i added the 256 video and 2 gig ram. so now, when i try the same process, ME wont boot, (this was the problem when i first added the 256 & 2 gig). with ME not booting, i cannot install both OS. i tried installing XP first and then ME but just the same, it wont boot with ME, and i cant open xp as well. so now here i am... i've installed xp but would really want to install ME as well (i have an old program that wont run in xp). is there a way to edit the sys.ini using dos so i can input the correct values. again, thanks a lot .... ronald
