I have a real mind blowing dilema here: I am doing a clean install on a new system using the Tyan Tiger S2460 mother board. I am using a recommended ddr register memory of 512(from the tyan site) I have two 1.2ghz amd athlon cpu's . I have one Maxtor 30.7 gig. hard drive installed and the Verto tnt2-m64 pci video card and had the Matrox G550 agp video card installed before changing to the pci card. I am booting up from a win 98 floppy start up and doing the fdisk on the drive. I then change my bios to boot from the cd-rom drive and then boot from the windows xp pro cd. I then format the drive to NTFS files and then all files from cd copy to the hard drive. Then when files are done copying, it reboots and i see a faint xp screen then I get the dreaded blue screen with a stop error code: Stop error code : 0x0000007e (0xc0000005) 0x8053a29d 0xf894d434 0xf894d134 I have received this error code no matter what I try. I have changed video cards, ram memory, check bios update, which my is the most recent bios update available, ect.... I have contacted tyan support and they do not know what the problem is either. I also went to the extent of purchasing another tyan mob s2460 while waiting on my rma to be processed on the original mob. Results are all the same. I even tried installing windows 2000 pro and receive a stop error of : 0x00000023 0x000e00c8 0xf241acdc 0xf241a934 0x8046b9e4 I guess the only thing I have not done so far is to try the only other o.s. that can be installed on this mother board and that would be NT . The O.S. cd's are OEM's and they have worked on other systems that I built most recently. I would really appreciate any assistance from anyone that can help , it has become a quest now .

you can't do fdisk from a 98 disk and expect to install 2000. you have to partition and format using the 2000 install disk. it's the same for XP. using a 98 disk will give you all kinds of errors.

jeff is kind of correct. you should be able to do it the way you are. i've had these same issues. the only other thing i would check would be to make sure you have the latest device drivers for your system. (BUS mastering, HDD controllers,...)

Are you using Athlon mp's chips. I dont think that regular Athlons support multiple processor systems.

All the articles I've read say that you MIGHT get away with the ordinary chips, but might is the word.
