I had my pc running Windows NT 4.0. I had the pc formatted as I wanted to install Windows 98 and therefore the PC had to be formatted in FAT thus overwriting the NTFS format. Though the formatting did take place smoothly, Windows 98 managed to run the setup program almost 80 % installing all the necessary files and also showed the startup screen at first attempt, however it gave an error saying
"ERROR: Unable to control A20 line ! XMS Driver not installed.... and furthur Himem,sys is missing.Windows has stopped."
Though himem.sys is in place, I feel the problem is somewhere else. I formatted the 8 GB hard disk twice to confirm but .. still the same problem.
Please help... this matter is urgent
