I have troubles using it in a FreeBSD 6.2 machine:

./mkflash_new.sh 256 pfSense.img.gz

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

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 |
| 8 GB CFLASH-G-8415-I 8,415MB 16,435,440 16,305 16 63 |
