6. In "Task Selection", choose "Drivers" and "Bootable ISO" by high-lighting them.
7. For intel select single driver
For amd select multiple driver
8. For intel Browse to the SATA driver folder which you extracted earlier(I named it "Floppy32Bit") and select either one of the .INF file, i suggest "iaahci.inf".
-for amd browse to raid 7xx, slect x86 and select the inf files.
SELECT ONLY x86.
9) A screen like below will pop-up, make sure it's "Textmode driver" and select all of them by holding CTRL+A key and choose "OK", the pictures below for intel installation.

11) Choose "Yes" to start the process.
12) Let it finish and choose "Next".
13) Finally, you can create your project as ISO image or burn it directly to CD-R under "Mode". choose "Direct Burn". You can put anything for "Label" but not too long. Choose "Burn" and you will be prompted again. You can also choose to create iso to burn using software such as nero.
14) Choose "Yes" to burn it to CD-R. Wait for it to finish and choose "Next"

Additional notes.-If your slipstreaming process unsuccessful, you can repeat the process but create a new folder and DO NOT USE THE SAME FOLDER.
