Hello I have Windows 95 OSR 2.5 and Windows C is 98 and I'll not have to install dosbox so functional stable and it crashes at the second stage of installation to time of detection device that is after rebooting the first time. I said that I have seen on the internet via youtube video DOSBox "Next-Gen" showing on Windows 9x and even dosbox Windows 98 3dfx card with dosbox emulate.

If someone can not to assist because I can not find any tutorial to install Windows 9x stable so dosbox, if possible with a 3dfx card.

In advance thank you

Edit: I specify that I want to run on dosbox host bone pc Windows Vista Home Premium 32 Bit Service Pack 2 and Windows 7 64-bit home premium and have games that do not work under MS-DOS but Windows 9x and works very poorly on Windows XP and Vista Next, 7, and which requires direct3d or even 3dfx.
