(I'm sending this again, because I never got a copy back myself, nor did I see it in the mail archives. If you go two copies, sorry for the inconvenience ;-) Hi, I created a custom picobsd bootflop, which allows one to boot a system, enter an IP address on the console and then telnet to it. The goal of this floppy is to remotely install a system, where the local involvement consists only in booting the system with the bootflop, and configuring the ethernet interface. This works great, except for one weird problem. I can't disklabel the disks (the disks are either unused or have a non FreeBSD disklabel on it). I use the disklabel procedure as described in disklabel(8). The boot flop is created on FreeBSD 4.2-STABLE. The transcript of the session is as follows: # dd if=/dev/zero of=/dev/da0 bs=512 count=32 32+0 records in 32+0 records out 16384 bytes transferred in 0.354870 secs (46169 bytes/sec) # fdisk -BI da0 ******* Working on device /dev/da0 ******* fdisk: invalid fdisk partition table found # dd if=/dev/zero of=/dev/da0s1 bs=512 count=32 32+0 records in 32+0 records out 16384 bytes transferred in 0.354167 secs (46261 bytes/sec) # disklabel -w -B da0s1 auto disklabel: ioctl DIOCGDINFO: Invalid argument disklabel: auto: unknown disk type ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is where it fails. Now comes the weird part. If I boot the system using the 4.2 RELEASE bootflop and use sysinstall to label and partition the system it works fine. So it is not the case that the bios/harddisk driver do not support the 'auto' disk type. As far as I can see, there are two possibilities: 1) sysinstall uses a different method for labeling/partitioning the disk 2) something is different or missing on my picobsd floppy, but I have no clue what it is (device, program, out of memory, kernel config) Does anyone has a clue what is going on? Does the ioctl provide a clue to a SCSI expert? Any help is appreciated, Frank To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
