sdi size when network booting

When building a network bootable image, how much space am I supposed to
allocate on my sdi disk if my image size after FBA turns out to be 200 Megs?
Exactly 200? 210? 250?



How can I calculate how much extra space I need to have on the sdi disk for
any given image size?



Thank you.
 
I am not sure I understand:



Step 1) In order for me to create a bootable image I must fist use the SDI
loader application and create a partition of a certain size so that I can
copy my XPe image right after FBA to that newly created partition. What's
the size of the sdi partition that I am supposed to create here???



Step 2) Once I am done with that, I use the cscript command to make another
sdi file that will be the one used by the network boot (Creating this file
is no problem)



So, what is the size of the sdi partition for a given XPe image size after
FBA as described on step 1. For example, if my XPe image after FBA is 100
megs is my sdi partition supposed to be 100, 105, 110???



Thanks.
 
Ok, now I understand.
You have skipped few steps.

1. You must run FBA from HDD on your target device. (Copy your image with
method that is convenient for you).
2. Then after the FBA you use image from HDD partition to make SDI image.

You can't skip this :(

I still don't know what is the size of the sdi that I should use!!



I have no problem creating a network boot; everything works fine, what I
don't know is the minimum allowable size of the sdi partition that I can get
away with.



If my image after FBA is 200megs and I make my sdi drive 200megs my system
crashes. If I make the sdi partition 250 megs (50 megs bigger than my
partition) everything works fine, but I am probably wasting a lot of memory
by allocating more space to the partition that I need!!



So what is the minimum sdi partition size that I can get away with?



Thanks
 
Rene if your partition size is much different from size set in TD your XPe
will likely crash. (This is license violation error)
You should tell us what error you see.

Also it is not important what is your image size in bytes but rather
partition size is what matters.
You should make sdi file directly from your post FBA partition so if your
partition on HDD is 200 MB and your image is working then it will work on
SDI file as well.

How much extra space you need. Well this will depend on how many log files
you were able to disable. You will need some space (few extra MB) to boot
your system.

Rene,

There is no right answer to your question, it basically depends on what
you've in your image, if the components in your runtime do not require a lot
of free space you should be ok with ~10MB of free space.

Thanks
