Sorry folks, this probably isn't a FBSD topic as such, more of a generic hw problem, I guess ... but maybe some tekram owner is able to give me advice. I'm having a bit of a problem booting from an IBM disk hooked up to a Tekram 390u2w controller. At boot-time the controller refuses to load the BIOS and hence boot from the SCSI disk. The 390 spits out a: "No BIOS disk found! SCSI BIOS not installed" According to the Tekram manual, this is normal if only a CD-ROM is installed. I get this behaviour with only the IBM disk on board. The strange thing is that the controller occasionally is able to find the disk allright and boot from it but most of the time is not. What should I look for? I took out all the other SCSI devices, so as far as I can tell, the problem should be in the controller, cabling or the disk itself. Maybe termination? If I boot off of an IDE disk, the sym driver finds the disk ok and although performance isn't stellar, things function as expected. Here's what dmesg says about the controller: sym0: <895> port 0x6c00-0x6cff mem 0xea000000-0xea000fff,0xea001000-0xea0010ff irq 9 at device 11.0 on pci0 sym0: Tekram NVRAM, ID 7, Fast-40, LVD, parity checking and the disk: <IBM DNES-318350W SA30> Fixed Direct Access SCSI-3 device 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled 17501MB (35843670 512 byte sectors: 255H 63S/T 2231C) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
