But many SCSI adapter makers, who use these chips, state that their SCSI card tested under 33MHz bus clock. LSI document says that 53c1000/1010 family has a 33/66MHz interface to work with both 33 and 66 MHz PCI slot, but I had a Tekram DC-390U3W, which uses 53c1010 chipset, works only at 33 MHz under FreeBSD. I am not sure who is wrong in these specifications. Maybe the BIOS can provide some useful information during the boot, such as, 53C1000-## during SCSI BIOS probe. The ## should be either 33 or 66. If the ## is 33, then you need a jumper on the motherboard to set 53c1000 to work at 33MHz? If it is 66, you need to ask the sym driver developer -- Gerard Roudier -- for help. -- ------------ Jin Guojun ----------- v --- j_guojun@lbl.gov --- Distributed Systems Department http://www.itg.lbl.gov/~jin M/S 50B-2239 Ph#:(510) 486-7531 Fax: 486-6363 Lawrence Berkeley National Laboratory, Berkeley, CA 94720 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
