Pk., MD 20742 Lines: 31 Distribution: world Message-ID: <3u8sul$4sr@amanda.cs.umd.edu> NNTP-Posting-Host: amanda.cs.umd.edu I have attempted to boot the floppies from both the 2.0.5R and 950622-SNAP leading to a "integer divide fault panic" after detecting SCSI devices, but before completing the boot. I have (according to linux): scsi-ncr53c7,8xx : at PCI bus 0, device 14, function 0 scsi-ncr53c7,8xx : NCR53c815 at memory 0xfefffc00, io 0xfc00, irq 9 Vendor: ARCHIVE Model: Python 25588-XXX Rev: 2.96 Type: Sequential-Access ANSI SCSI revision: 02 Detected scsi tape st0 at scsi0, channel 0, id 4, lun 0 Vendor: MICROP Model: 2217-15MQ1001901 Rev: HQ30 Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 5, lun 0 Vendor: DEC Model: DSP5400S Rev: 427L Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sdb at scsi0, channel 0, id 6, lun 0 All of these devices work under linux. When I boot the freebsd disk with the DEC disk connected to the SCSI bus, the "integer divide fault" occurs. If I remove the disk, I can successfully boot to the freebsd install program. I see two potential problems 1) Disk is currently partitioned by OS2 fdisk for 2 equal linux partitions of 1949664 1K blocks. I partititioned the disk using a Future Domain 1670 controller. I replaced the controller with a NCR 815. Could this lead to geometry problems that could lead to the panic? 2) Does freebsd support disks >2GB? John
