Is 
this a M-Sys DiskOnChip 2000 ? if so this may help.

Just a 
note you will also need to check that the drivers work on RH 6.1 as I know 
the current ones available.1 (at the M-sys) work on RH 6.2 (not sure if they 
will work as I have not used RH6.1).
The 
older drivers (come with 121 utilites for kernel 2.0.x 2.2.X 2.4.X )though they 
appear to work on later systems I am still trying to remove ramdom systems 
failures using the old drivers on the new 4.2 DiskOnChip 2000 series even though 
I have system out there that have been working for two years + on kernel 2.0.35 

See 
also o'reilly online books and get the Linux device drivers by 
alessandrorubin & jonathan corbet (can send if you would like) as the way 
drivers work has chamged

If you 
are using the new 5.1 utilites not all the instructions are accurate for placing 
a bootable image on the disk as the addressing of the new dinfo for finding the 
DiskOnChip provide an address as 0xd8000, 0xda000, 0xdc000, 0xde000 drop the 
extra zero at the end) d800 not 8000.  you also may have trouble with the 
getimage putimage functions but I have not checked these yet, have only 
used 121 version.  Also are you using a ramdisk, this will save the 
read-writes to the disk which has a limit, and since you are filling up the disk 
may cause trouble later since the part of the disk left over after the system 
has been placed on will not be much, (we moved to a 32MB disk for this reason 
even though the 16MB disk using a system that fit within this did not leave 
enough room for the life of the machine we were developing)

Notes    1) have you checked the requirements for the 
TrueFFS driver and what it requires from linux, you may be able to strip it down 
if you are not using the extended functions ? this may help

2) If the disk cam formatted the a 
bootable dos system you masy have trouble reformatting for linux do not as we 
why as my supplier can not explain it either

  to reduce the size

  Hi,

   I trying to Port Rh Linux 6.1 in a 8 MB 
  Diskonchip flash disk. If I copied the required files in to the disk on chip, 
  it requires 16 MB of memory. I think the Library files are taking most of the 
  space.

  Is it possible to port the Linux in 8Mb of flash 
  disk..?

  Is it possible to port the Linux without library 
  files.? I have tried to compile a df.c file with -static option but the size 
  of the static df exe is 1392767. The size of df exe without the -static option 
  is 14132, but it requires libc.so.d and ld-linux.so.2.

  Is there any other option to compile the files 
  statically..?

  Please help me to port the linux in 8 MB of flash 
  disk.

  with regards,

  Shankar R
