I did a new install of 4.0-19990311-SNAP onto a system that was previously running 3.0-19991105-SNAP. The 3.0 system was using the old boot blocks. The 4.0 install was via ftp, and worked without a problem. However, upon rebooting the machine, it would not boot. The 2nd stage boot loader had not been installed. The only way to boot was to type in /boot/loader and it would then boot up. Upon determining this was the problem, I then ran: fdisk -b to rewrite the sector 0 boot code. This had no effect. I then ran: boot0cfg -B this had no effect. Finally, I tried: disklabel -B da0 which also had no effect. I re-installed the 4.0 system from scratch again thinking I must have really messed something up. No effect, still no normal boot. Out of frustration I ran the following: dd if=/dev/zero of=/dev/da0 bs=512 count=2048 to wipe out the front-end of the boot disk. I then re-installed the 4.0 system a 3rd time and it now boots normally. I am unable to explain why this happened, but hope that someone with more experience with the sysinstall/boot code can shed some light on it. An additional item with respect to sysinstall. I select [All] of the distributions to install, which includes compat22. Well, compat22 is not built by the 4.0 system. Looking at the last snap on ftp.freebsd.org (4.0-19990211-SNAP) shows that compat22 is: lrwxrwxrwx 1 2035 207 19 Feb 12 04:09 compat22 -> ../current/compat22 Could someone explain why this isn't built at 4.0, or what is going on with it? (I build my own -SNAP releases daily, and the latest 4.0 builds are looking really stable, at least of uniprocessor systems). Comments, critiques, and helpful hints appreciated! Thanks!
