Hi: I am trying to upgrade Windows 95a to Windows 98 on a Gateway Pentium 133 processor. However, I keep getting a suwin error with the details saying that "suwin caused general protection fault in module SUWIN.exe at 000c:00000225." Before this error occurs, the setup program was setting up Install Shield which went upto 100%. I looked up the setuplog.txt and found the following: [OptionalComponents] [System] [NameAndOrg] [RunningApps] [Destination] [] fsCmosAVCheck: Attempting CMOS Anti Virus Test FYI, I did uninstall McAffee VirusScan before attempting the upgrade. Also, I bought this computer with 16 MB EDO RAM originally to which I added 64MB EDO RAM. (I have tried installing only with the new RAM with no success). This PC also has a new Maxtor 20 Gig drive which is the master drive (C:) with the old 1.6 Gig drive being the slave. When I installed the Maxtor drive, I x-copied all the files to the new drive to be able to boot from it. I think I have FAT 16 as my Maxtor is partitioned into 10 partitions. Does somebody have any idea what my problem might be, and how to fix it? Thanks.

I finally got win 98 installed (with the help of Microsoft tech support) but not without a lot of heartburn. I don't know what exactly was causing the suwin error - I think it was the overlay software used by Maxtor to partition my Maxtor 20GB hard disk. Since my original bios did not support such large hard drives, Maxtor used something called ez-bios. I discovered this may be the problem because I was able to install on my second older hard drive (2.1 GB). After that I had to do a fresh install on the Maxtor 20 GB, with the help of the E-Z bios (I think). Hope this helps for others facing a similar problem.
