63 ------------------
65 The usage of the word (two bytes) that "rdev -r" sets in the kernel image is
66 as follows. The low 11 bits (0 -> 10) specify an offset (in 1 k blocks) of up
67 to 2 MB (2^11) of where to find the RAM disk (this used to be the size). Bit
70 the RAM disk dynamically grows as data is being written into it, a size field

109 -----------------------------------------------
120 a) Decide on the RAM disk size that you want. Say 2 MB for this example.
130 	mke2fs -vm0 /dev/ram0 2048
135 d) Compress the contents of the RAM disk. The level of compression
139 	dd if=/dev/ram0 bs=1k count=2048 | gzip -v9 > /tmp/ram_image.gz
149    size would be reasonable. Make sure offset+size of ram_image.gz is
159 	rdev -r /dev/fd0 49552
