Hello, Thank you for taking the time to read this message. Four days ago I went to a computer show and bought an Asus P4C800-E deluxe mobo, 1024MB or RAM, Intel Pentium4 3.0Ghz CPU. The next day I removed the old Asus A7V133 mobo and installed the P4C800-E. Installed all the cards etc. I fired it up and this is what I saw at post: First the post screen with the Asus Logo. Then it went to a blank screen that stated: SATA 378 TX2 plus (tm) BIOS 1.00.0.3 c 2000 -2005 Promise Technology All rights reserved Then the system was snooping around for something which stated: Detecting .......... Then : No device found ! Bios not installed. The system went to the usual Start Windows normally, safe mode etc. I selected normally and the system just kept on looping from the beginning LOGO to the selection of Start Windows normally, safe mode over and over. Finally, I said the heck with it and formatted the H.D.D. and install windows XP. This time the system fired up into Windows XP to the desktop. I continued to get the same screen after the post and LOGO: SATA378 TX2 plus etc.etc. etc. I was wondering if "NO DEVICES" were found and "BIOS NOT INSTALLED" then why was the system booting into Windows XP :suspiciou I went to Asus.com and got the newest BIOS, created a bootable disk and Flashed the BIOS by using AFUDOS ..... afudos /i<filename> where <filename> was the name of the new BIOS. The new BIOS was installed. I still keep on getting the second screen No Device found ! BIOS not Installed I am now thinking the system is looking for SATA devices and BIOS. I am not currently using any SATA device. I do not know what is happening.... Could one of you "Pro's" straighten me out and let me know what is happening ? Any information will be appreciated. Thank you. Rick M.
