I built a similar system last December using a PII 350 on a FreeTech motherboard, a Diamond V550 AGP, and an Adaptec 2940AU controller. I also got the timeout failures and other SCSI failures during the boot. Sometimes it did not even find the SCSI board. I moved the SCSI controller to different PCI slots and found that the change in position affected the recognition. In particular, You should not place the SCSI board into PCI slot 1 or 5 since these share an interrupt with the AGP slot. Additional problems were solved by getting updated drivers for the SCSI - of course this only affected operation after a boot. I am running Windows NT. Also, check the SCSI speed for each device - some of my settings were too fast for the devices connected to the board. Hope this is of some help.

No operating system currently installed. CPU - PII 350 MHz Motherboard - ASUS P2B (Has an AWARD BIOS v4.51PG revision 10008) SCSI Controller - Adaptec 2049 Ultra Wide V1.25 BIOS Quantum Fireball 6.4g SE Diamond V550 AGP vide card I receive a "time our failure during SCSI inquiry" error message when the controller attempts to locate the devices on startup, followed by a "SCSI BIOS not installed". I went to the SCSI utilities and could not get the device to be recognized. Curious about the people moderating your messages? Visit our staff web site: http://nospin.com/pc/staff.html
