Windows 7 64 bit

Has any of you went from 32 bit to 64 bit 7?

Windows 7 32 bit (main laptop), XP/Ubuntu (netbook)

I now have Windows 7 installed! It took some persuading that the driver in the folder I was pointing it to was what I really wanted to install, I can't remember exactly what I did without the computer in front of me (reluctant to look here as I'm on a work computer and if any IT people walked past I'd probably get told off as they'd think I was actually trying to mess up hardware drivers rather than just see what the menus are) but I think rather than looking in a folder for a driver I had to do something slightly different to get it to pick a particular file. Otherwise even if it found the driver it refused to install it on the grounds of assuming the current one was better. After selecting the .sys file it gave a choice of three, I picked the most generic one (name not longest or shortest) and then everything worked.

So I tried restarting my laptop and ran the upgrade setup again, and got the same error message.

Any ideas on what I need to do to get it to upgrade? I tried searching all over and can not find a newer version than what I have (2.5.1540.48).

All correct me if I'm wrong, but there is no such thing as a ATI video card driver for RAID AHCI?
What Mike is looking for are Storage devices support?

I could be a total fool in this?

Windows 7

Hello guys!

I have a Dell Inspiron 1721 and I'm thinking about upgrading the OS from Windows Vista Home Premium to Windows 7 Ultimate. As I read on this and other forums, there has been a problem installing Windows 7, but I see you have managed to pass this problem. So I have a few questions:

Did you try to do a clean install of Windows 7 or you just upgraded from Windows Vista?
If i try to do a clean install, will it let me to install it and use it? (except the part with the ATI AHCI Compatible RAID driver, where I understood that I have to manually upgraded).

Thanks in advance!

I upgraded (to home, not ultimate) and it worked easily after the RAID upgrade. I haven't even found any programmes that need reinstalling yet.

What about performance? At least, my Dell sucks with Windows Vista installed. It takes up to 4-5 minutes to boot (with Widget Bar and Search Indexing off)

I think it boots a lot faster, I haven't actually timed it with either OS but I think it was in the region of 10 minutes with Vista from pressing the on button to actually being able to operate Firefox, on 7 it's more like 5. CPU usage is a lot lower.

win 7

Found a easier way.

download driver from here. <-32 bit <- 64 bit

  1. Extract and Copy the driver (ahcix86s.sys)
  2. Go to C:\windows\system32\drivers and backup the driver ahcix86s.sys (likely has a 2007 date)
  3. Paste new driver (ahcix86s) into this folder
  5. Run Windows 7 installer
  6. done

windows 7

i am very new at this and so i dont know what you all are really talking about, but i have a problem and i strongly believe it is to do with this.
here my story; )
i have built my pc myself,
i have a gigabyte motherboard
nvidia 8600 512mb gfx
amd athlon 64 x2 dual core 4800+ 2.50 ghz processor.
2gb 800 mghz ram
i tried using vista on this set up, and i kept getting blue screen restart, randomly.
so like at any random point my pc would freeze and instantly go to blue scran dump my ram and restart. this was extremely annoying, so i went back to xp (this problem didnt happen on xp) now i recently installed windows 7 and it is stil happening, i am 99% sure it is to do with my drivers, i downloaded my motherboard drivers but they didnt help, at the same website i also found the ahcix86s file, i downloaded that but i dont know where to extract it or how to use it and i dont even know if it will help.

any ideas and help would be very appreciated.
