75Compressed cpio images
76----------------------
77
78Recent kernels have support for populating a ramdisk from a compressed cpio
79archive, on such systems, the creation of a ramdisk image doesn't need to
80involve special block devices or loopbacks, you merely create a directory on
81disk with the desired initrd content, cd to that directory, and run (as an
82example):
83
84find . | cpio --quiet -c -o | gzip -9 -n > /boot/imagefile.img
85
86Examining the contents of an existing image file is just as simple:

14 2005-05-19 v0.1 Initial version, based on incomplete docs
15 and analysis of misbehavior with the standard driver
16 2005-05-20 v0.2 Extended the input buffer to avoid losing
17 random 64-byte chunks of data
18 2005-05-21 v0.3 implemented chars_in_buffer()
19 turned on low_latency
20 simplified the code somewhat
21 2005-05-24 v0.4 option_write() sometimes deadlocked under heavy load
22 removed some dead code
23 added sponsor notice
24 coding style clean-up
25 2005-06-20 v0.4.1 add missing braces :-/
26 killed end-of-line whitespace
27 2005-07-15 v0.4.2 rename WLAN product to FUSION, add FUSION2
28 2005-09-10 v0.4.3 added HUAWEI E600 card and Audiovox AirCard
29 2005-09-20 v0.4.4 increased recv buffer size: the card sometimes
30 wants to send >2000 bytes.
31 2006-04-10 v0.5 fixed two array overrun errors :-/
32 2006-04-21 v0.5.1 added support for Sierra Wireless MC8755
33 2006-05-15 v0.6 re-enable multi-port support
34 2006-06-01 v0.6.1 add COBRA
35 2006-06-01 v0.6.2 add backwards-compatibility stuff
36 2006-06-01 v0.6.3 add Novatel Wireless
