Hi, I have a requirement to perform the unattended installation but my problem is this that I am not suppose to customize the winXP iso. I wanted to provide the winnt.sif through floppy , and also need to provide the lsi driver through floppy. I have tried many other ways to perform this scenario,but could not get any success on this. Can any one please give me some suggestions, whether it is possible or not Or what alternative can I have for performing the unattended installation without customizing the xp iso image. Any suggestion will be great help for me, please suggest me something on this, Just would like to explain my scenario once again, 1. WinXP unattended installation, but now suppose to customize the ISO. 2. Provide the winnt.inf file through floppy, (This is working for ide disk desktop) 3. Also provide the disk drivers through same floppy drive. (Need suggestions on this, how can I achieve it.) Suggestion will appreciated .
