Cramfs - cram a filesystem onto a small ROM cramfs is designed to be simple and small, and to compress things well. It uses the zlib routines to compress a file one page at a time, and allows random page access. The meta-data is not compressed, but is expressed in a very terse representation to make it use much less diskspace than traditional filesystems. You can't write to a cramfs filesystem (making it compressible and compact also makes it _very_ hard to update on-the-fly), so you have to create the disk image with the "mkcramfs" utility. Usage Notes ----------- File sizes are limited to less than 16MB. Maximum filesystem size is a little over 256MB. (The last file on the filesystem is allowed to extend past 256MB.) Only the low 8 bits of gid are stored. The current version of mkcramfs simply truncates to 8 bits, which is a potential security issue. Hard links are supported, but hard linked files will still have a link count of 1 in the cramfs image. Cramfs directories have no `.' or `..' entries. Directories (like every other file on cramfs) always have a link count of 1. (There's no need to use -noleaf in `find', btw.) No timestamps are stored in a cramfs, so these default to the epoch (1970 GMT). Recently-accessed files may have updated timestamps, but the update lasts only as long as the inode is cached in memory, after which the timestamp reverts to 1970, i.e. moves backwards in time. Currently, cramfs must be written and read with architectures of the same endianness, and can be read only by kernels with PAGE_CACHE_SIZE == 4096. At least the latter of these is a bug, but it hasn't been decided what the best fix is. For the moment if you have larger pages you can just change the #define in mkcramfs.c, so long as you don't mind the filesystem becoming unreadable to future kernels.

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
