This is specific to Commodores that have two 4464 RAM chips (32k each, in later 64s and the 64C).

UltiMem64 replaces the two 4464 DRAM ICs on newer Commodore 64 motherboards (and can be installed in older 8-IC 4164 DRAM based motherboards using the DRAMCarrier PCB) and provides access to 2 megabytes of direct memory access (not REU access). The memory is instantly available when requested, no DMA needed. The Color RAM IC installs in the 2114 space on motherboards containing a 2114 Color RAM and provides access to 64 kilobytes of Color memory nybbles.

To make this happen, it has its own MMU.

The Brewing Academy LLC is located in Woodland, California, USA near Sacramento. We have been in Woodland since 2015 and have been operating in one form or another since 2005. In the past, we noticed that a lot of cool stuff came out for the Atari and the TI 99/4a and the Commodore, but that it always disappeared after awhile making it incredibly frustrating AND expensive for people to use their older computers. So, we decided to change that1 Our belief is that we find the coolest retro stuff we can and make sure we keep it available as long as possible.

Back in 2008, the idea came up to create a cycle exact floppy disk drive emulation of the Commodore 1541 drive, and embed this emulated drive in a cartridge for the Commodore 64 home computer. Today, the 1541 Ultimate and related products have become indispensable extensions for the Commodore 64 and 128 computers. According to some users, it has completely changed the way they use the old machine as it nearly eliminated the need for real floppy disks. In 2016, the Ultimate-II+ cartridge was released. This is the latest version of the 'Ultimate' cartridge.

If you find yourself in a position in which you're running Arch Linux and your file systems are based on LVM, RAID, or both, and when you upgrade your kernel your system won't boot because the kernel isn't running the lvm2 hook, here's how to fix it.

0. create an arch live stick and boot it
1. mount your root partition to /mnt on the live stick
2. mount your /proc partition to /mnt/proc using mount -t procfs proc /mnt/proc
3. mount your /sys partition to /mnt/sys using mount -t sysfs sys /mnt/sys
4. mount your /dev partition to /mnt/dev using mount -t tmpdevfs dev /mnt/dev
5. mount your /boot partition to /mnt/boot
6. chroot into /mnt using chroot /mnt
7. now perform pacman -Syu and watch your kernel being built.
8. finally type exit and reboot. remove your stick and boot into your now working arch linux.
