Hi, I recently purchased the book "The Complete FreeBSD". I tried to install the UNIX system but it failed to boot. The last message it says is :" Panic: cannot mount root". Here is the detailed process I went through: The machine I have is a Cyrix 150 MHz with 32 Meg of RAM. I have two hard drives in this machine: the primary master is a 2 gig IDE and is used entirely by Windows 95 OEM Release 2. The primary slave is a 1.2 gig IDE (1227 Meg) drive which I intend for FreeBSD. The motherboard is capable of detecting hard drives and here is what it saids: Hard Disks Type Size CYLS HEAD PRECOMP LANDZ SECTOR MODE Primary Master 2002 970 64 0 3881 63 LBA Primary Slave 1339 2595 16 65535 594 63 LBA I booted from CD-ROM and got into the FDISK screen. The hard drive is empty, so I pressed "A" to use the entire disk. FreeBSD created 30 Meg for "/", 73 Meg for "swap", 32 Meg for "/var" and the rest for "/usr". Then I quit and used the custom installation without the boot manager (the middle choice of the boot manager selection screen). Everything then went on fine except that I cannot find the "Quit" choice on the "Machine Configuration" screen. So I chose "Exit" from the menu, "Exit" again to get back to the original screen and chose "Exit Install". Then the machine reboots and prints the boot messages and went on printing the information of hard drives, card information, etc, until it says "panic: cannot mount root". Here are the last few lines of the screen: ... lnc0 not probed due to I/O address conflict with ed0 at 0x280 ze0 not found at 0x300 zp0 not found at 0x300 npx0 flags 0x1 on motherboard npx0: INT 16 interface panic: cannot mount root syncing disks... done Automatic reboot in 15 seconds - press a key on the console to abort --> Press a key on the console to reboot <-- After the machine rebooted, I started with the installation CD again, and went into the "DISKLABEL" and found that except the swap partition, all the text in the "Mount" column saids <none> and the Newfs saids "*". I think that is the problem since "/" is not mounted. So I use M to mount them and installed again. But the same thing happened like last reboot. Seems that the software just cannot mount the partitions correctly. I wonder if there is something I did wrong or something wrong with my hardware configuration. Then I used Linux boot and root disk to boot and type "FDISK /dev/hdb" at the command prompt, and Linux report: 64 heads, 63 sectors, 648 cylinders Device Boot Begin Start End Blocks ID System /dev/hdb1 * 1 1 649 1307848+ a5 BSD/386 Partition 1 has different physical/logical endings Phys=(1023,15,63) logical=(648,47,63) Partition 1 does not end on cylinder boundary Phys=(1023,15,63) should be (1023, 63, 63) Later on, I deleted the entire installation and use the CMOS hard drive auto detection and used NORMAL mode on the primary slave drive (looks like below) and reinstalled FreeBSD and still failed.
