Date: 7 Aug 1994 17:00:16 -0700 Organization: Tektronix, Inc., Beaverton, OR, USA Lines: 32 Message-ID: <323sig$2n1@tekgen.bv.tek.com> NNTP-Posting-Host: tekgen.bv.tek.com All of my problems regarding the BT445C are fixed, thanks to all the suggestions from net.freebsd'ers. Throughout this ordeal, there are a few points that surfaced that could help anybody else trying to get a BT445C SCSI VLB card going in their FreeBSD box. Here's a summary: 1) The BT445C is NOT the same as the BT445S for which their is a wealth of FAQ info on setting up. The BT445C has NO jumpers to set IRQ's, this is all done in EEPROM from the setup bios. The card functionally seems identical to its predecessor though, probably due to the same chipset. :) 2) My computer just flat wouldn't work if booted from the kcopy_bt floppy, it would die shortly after the ISA probe. Changing the EEPROM interrupt to IRQ12 helped a little, but the kernel still couldn't talk to the card correctly. The solution I came to was recompiling the generic_bt kernel and pointing the bt0 driver to IRQ11 (BT445C default) on a different machine and using that to boot from. I suspect the above mentioned problems are something the new EEPROM version of the card throws into the equation (maybe a firmware bug??). If anybody needs a copy of the compiled kernel for IRQ11 or the whole boot floppy that saved my weekend from being a total disaster can send me email. If there is enough response, I will post it on an anonymous ftp site (either locally or somewhere well known). Thanks again for everybody's help.
