-Unfortunately, the Intel LANDesk Service Agent II prior to version
-0.99h (PXE PDK V2.4) seems to have a host of serious bugs.  Among
-other things, it requests the TFTP "blksize" option, but will be
-mortally confused if this option is actually accepted by the server!
-There are three possible workarounds for this bug:
-
-1. Use a TFTP server with doesn't support "blksize".
-
-   Unfortunately, PXELINUX requires the "tsize" option to be
-   supported, and it is very unusual for TFTP servers to implement one
-   and not the other.  Both the tftp-hpa and atftp TFTP servers (see
-   above) therefore can be configured to disable the blksize option.
-   Use "-r blksize" for tftp-hpa, "--no-blksize" for atftp.
-
-2. Use MTFTP for the initial bootstrap.  You need an MTFTP server with
-   the appropriate DHCP setup to do this.
-
-3. Use appropriate DHCP options that the client will attempt MTFTP
-   before trying conventional TFTP.  It seems that the client will not
-   request the "blksize" option if it has tried MTFTP and failed.
-   These DHCP options are beyond the scope of this document.
-
-These systems also seem to break if PMTU discovery is enabled on the
-TFTP server.  This has to be disabled in the kernel on the TFTP
-server.  On Linux, you can disable PMTU discovery by setting:
-
-	echo 1 > /proc/sys/net/ipv4/ip_no_pmtu_disc
-
-Note that this may cause bad performance for other services on the machine.
