Hello, Trying to install 5.4 on a box that had previously run 5.3 just fine and before that 5.2. I wanted to do a fresh install vs. an upgrade and unfortunately this box can not boot from CD, the install is also headless. I created the floppies, then mounted boot.flp and put a boot.config file on it with "-h" contained within. I then booted the install, got through the point where i had to reinsert the boot.flp disk, after the two kern*.flp disks, and the system went in to a loop. Here's the repeating error: spec_getpages:(md0) I/O read failure: (error=5) bp 0xc94fb9ec vp 0xc1d42d68 size: 36864, resid: 36864, a_count: 36864, valid: 0x0 nread: 0, reqpage: 0, pindex: 459, pcount: 9 vm_fault: pager read error, pid 1 (sysinstall) At first i thought it was a media issue or a download issue, but i've verified the md5 signature of the image, which came off a 5.4-RELEASE cd-rom, and have recreated four boot.flp floppies with the same result. My dmesg is below. Any input welcome. Thanks. Dave. dmesg: Uncompressing ... done Console: serial port BIOS drive A: is disk0 BIOS drive C: is disk1 BIOS drive D: is disk2 BIOS 638kB/392192kB available memory FreeBSD/i386 bootstrap loader, Revision 1.1 (root@harlow.cse.buffalo.edu, Sun May 8 05:59:07 UTC 2005) Loading /boot/defaults/loader.conf /kernel text=0x444168 \ Insert disk labelled "Kernel floppy 1" and press any key... | Insert disk labelled "Kernel floppy 2" and press any key... data=0x7d5c8+0x4fc78 syms=[0x4+0x5b390+0x4+0x706c9] Insert boot floppy and press Enter /acpi.ko text=0x414fc data=0x1dc4+0x112c syms=[0x4+0x7670+0x4+0x9d05] zf_read: fill error Copyright (c) 1992-2005 The FreeBSD Project.
