the needed kernel and put it in /usr/src. + Create a directory for the source and unpack it. + For example: + <verb> + cd /usr/src + rm -f linux + mkdir linux-2.3.51 + ln -s linux-2.3.51 linux + bzcat linux-2.3.51.tar.bz2 | tar xf - + </verb> + <p> + Now configure your kernel. + You might, for example, use <tt>make menuconfig</tt> and do the + following: + + <itemize> + <item>Go to <em>Code

+ <item>Enable all chipsets' support for AGP + </itemize> + + <p>It's recommended that you turn on MTRRs under <em>Processor type + and Features</em>, but not required. + + <p> + Configure the rest of the kernel as required for your system + (i.e. ethernet, scsi, etc) + <p> + Exit, saving your kernel configuration. + <p> + Edit your /etc/lilo.conf file. + Make sure you have an image entry as follows (or similar): + <verb> + image=/boot/vmlinuz + label=linux.2.3.51 + read-only + root=/dev/hda1 + </verb> + <p> + The important part is that you have /boot/vmlinuz without a + trailing version number. + If this is the first entry in your /etc/lilo.conf AND you + haven't set a default, then this will be your default kernel. + + <p> + Now compile the new kernel: + + <verb> + cd /usr/src/linux-2.3.51 + make dep ; make bzImage + make modules ; make modules_install + make install + </verb> + Note that the final part, make install, will automatically run + lilo for you. + <p> +

There are two potentially interesting things + * about this implementation: + * + * 1) The table is power-of-two sized. Prime sized tables are more + * traditional, but do not have a significant advantage over power-of-two + * sized table, especially when double hashing is not used for collision + * resolution. + * + * 2) The hash computation uses a table of random integers [Hanson97, + * pp. 39-41]. + * + * FUTURE ENHANCEMENTS + * + * With a table size of 512, the current implementation is sufficient for a + * few hundred keys. Since this is well above the expected size of the + * tables for which this implementation was designed, the implementation of + * dynamic hash tables was postponed until the need arises. A common (and + * naive) approach to dynamic hash table implementation simply creates a + * new hash table when necessary, rehashes all the data into the new table, + * and destroys the old table. The approach in [Larson88] is superior in + * two ways: 1) only a portion of the table is expanded when needed, + * distributing the expansion cost over several insertions, and 2) portions + * of the table can be locked, enabling a scalable thread-safe + * implementation. + * + * REFERENCES + * + * [Hanson97] David R.
