Script to resize embedded images

[marzl]

Hi,

New in this Forum, i say hello to everyone interested.
I have recreate a skript to create 128, 256, 512 or 1gb Images out of the original 64mb embedded one.
Works only on FreeBSD, feel free to modify it for Linux.

How to use:
Save skript in your homedir.
#> mv mkflash_new.txt mkflash_new.sh
#> chmod +x mkflash_new.sh
Download latest Snapshot from http://www.pfsense.com/~sullrich/
Get pfSense.img.gz from there and place it in your homedir
Unpack pfSense.img.gz with
#> gzip -d pfSense.img.gz
Be shure to get root-rights
#> su
execute skript like:
Usage: /home/marcel/mkflash_new.sh {128|252|512|1024} {Originalimage}
Example: #> /home/marcel/mkflash.sh 128 /home/marcel/pfSense.img

Voila, take a look on the new image-file:
pfSense-128MB.img.gz
pfSense-128MB.img.gz.md5

Have fun,
Marcel

edit: changed heading to resize image….
mkflash_new.txt

Please, help!

It seems there is no support fpr Memory Disks on your System.
Does a```
#> kldload /boot/kernel/geom_md.ko

[bellera]

kldload /boot/kernel/geom_md.ko

kldload: can't load /boot/kernel/geom_md.ko: File exists

Any other idea?

Thanks,

Josep Pujadas

[marzl]

The Sourceimage has to be decompressed FIRST!

Use```
#>./mkflash_new.sh 256 pfSense.img

[bellera]

I'm very sorry!

I forgot gunzip the image file before running the script …

Many thanks!

What values should i use inside the following variables:

• flash_MB

• conf_MB

• heads

• sectors

for a 2 GB CF card
if i wanted to modify the script(http://wiki.pfsense.com/wikka.php?wakka=FlashHowToSkript ) to support 2 GB cards?

Hello!

I don't know if it is standard, but I found at http://www.industrialcompactflash.com/datasheets/wincflash.pdf :

Table 48: Product Capacity & Part Numbering

| Card Capacity Part Number Real Capacity Total Sectors/Card (Max LBA+1) Cylinders Heads Sectors |
| 128 MB CFLASH-G-128-I 131MB 256,512 1,002 8 32 |
| 256 MB CFLASH-G-256-I 262MB 513,536 1,003 16 32 |
| 512 MB CFLASH-G-512-I 526MB 1,028,160 1,020 16 63 |
| 1 GB CFLASH-G-1024-I 1,054MB 2,060,352 2,044 16 63 |
| 2 GB CFLASH-G-2048-I 2,118MB 4,136,832 4,104 16 63 |
| 4 GB CFLASH-G-4204-I 4,204MB 8,211,168 8,146 16 63 |
