yep used something similar. |

Be very careful with your lilo options. Make sure the specify what the boot |
| 25 |
device is at bootup (not /dev/sda1 when its attached to you card read/ |
| 26 |
writer). I remeber I did something with the bios=0x84(?) options in lilo to |
| 27 |
make it work (I had a harddrive and a compact flash to that may of been |
| 28 |
related). I'll email my former collegue to attempt to obtain the lilo |
| 29 |
configuration. I do remember facing a similar problem. lba related maybe but |
| 30 |
I can't remember exactly. |
| 31 |

| 32 |
Have you tried grub as an alternative? |

I haven't tried processor optimisations. |

Depends on your application. Have you enough spare ram to do this and is the |
| 52 |
access speed realy critical. By default a lot of ram gets used as a disk |
| 53 |
buffer anyway- and better still it gets freed if application need it. Measure |
| 54 |
the performance for your application. There are some fast access compact |
| 55 |
flash cards around more designed for the photography market. |

Look at the serial conole options for the kernel and lilo if you havent' |
| 65 |
already. |

| 70 |
|
| 71 |
crossdev = emerge crossdev |
| 72 |
uclibc buildroot = still being worked on although there is an exampe in bug |
| 73 |
29312 (http://bugs.gentoo.org/show_bug.cgi?id=29312) |
| 74 |
base-layout lite = still in design phases. |
| 75 |
|
| 76 |
If your arch is the same on both machines. Compile binary packages with the |
| 77 |
correct optimisations and to a binary install onto the compact flash. Use the |
| 78 |
"env ROOT=(CF mount point)" to install them. Always do a pretend first as I |
| 79 |
have seen some occasion pecularities where it doesn;t want ot install to |
| 80 |
$ROOT (ref http://bugs.gentoo.org/show_bug.cgi?id=34887) |
| 81 |
|
| 82 |
To save disk space do a bind mount (or symlink) on the CF /usr/share/doc some |
| 83 |
other documentation directories (/usr/share/info /usr/share/man) to local |
| 84 |
disk space. |
