• CD2 does not boot on the alpha, as had been planned. Instead, you must use the floppy install method. This is not significantly harder..

• Some rarer PC BIOS's do not like the hardrive bootblocks when used as a MBR. The symptom is that the BIOS says "READ ERROR" when booting, but everything suggests it should work fine. In those cases, it is sufficient to install OS-BS or some other primary bootloader as the main MBR, then install OpenBSD in a partition all by itself starting at a non-zero offset. For instance, start OpenBSD at track 64 or so.
• The i386/X11/SUMS.md5 file contains 4 incorrect MD5 checksums. These have been corrected on the ftp mirrors. The correct lines are: MD5 (X33doc.tgz) = 6aa0be7987f9a3cf32a63b5ea9a83b39
  MD5 (X33html.tgz) = 6ba39d41aef7c75c35a0533275c6f8c0
  MD5 (X33ps.tgz) = ea49fc1b12c17fc16ece7d0e4ad4ee06
  MD5 (RELNOTES) = 689fda20596a4eb82f86ded51efb01f4
  

• The amiga install has a flaw wrt Tseng based graphic cards: when entering multiuser mode the console won't get a login prompt. This is due to a problem in the shipped /dev/MAKEDEV script. To fix, enter single user mode and do:

  # cd /dev
  # sh MAKEDEV ttye6
  

• The sparc X11R6.3 xdm-config files reference /usr/X11R6.3/... This is due to X11R6.3's default config file contents. To fix, su and type:

  # cd /usr
  # ln -s X11R6 X11R6.3
  

• The sparc "single floppy install disk" has a problem when you specify "dumb" in response to the terminal type query. As a work-around first specify an invalid terminal such as "bogus" and when prompted again for a terminal type, enter "dumb" and it will work correctly.
• When netbooting an older sparc system such as a Sun4 or Sun4c, the boot may hang up at the end of the tftp transfer of the bootstrap due to the tftp transfer working in 512-byte blocks. If this occurs create a "padded" version of the bootstrap (boot or zboot) as follows:

  # cd /tftpboot
  # dd if=boot of=newboot obs=512 conv=osync
  # mv newboot boot
  

• When using the X11R6 binaries from the 2.1 release you will get errors like:

  # mkfontdir
  mkfontdir: undefined symbol: 'astpending' 12
  Segmentation fault (core dumped)
  

  this is due to a little problem affecting the compatibility between the OpenBSD/arc port (on which the X11R6 clients were build) and OpenBSD/pmax. You can work around this problem by using the arc version of the shared libc instead of the pmax one. You may get a copy of the OpenBSD/arc 2.1 libc.so.16.1 from here . Simply download it and do the following:

  # cd /usr/lib
  # mv libc.so.16.1 original_libc.so.16.1
  # cp /where_you_have_downloaded_it_to/libc.so.16.1 .
  # chown root.bin libc.so.16.1
  # chmod 444 libc.so.16.1
  

  Please be careful while doing this - because the libc is a very sensitive part of the system. You can remove the original_libc.so.16.1 after the next reboot if everything is working fine.
