I'm having trouble finding info on how to convert sector size (*if that's really what i want to do?) to something easier to understand.
I'm trying to copy the MBR from a bootable SD Card to another SD Card or image file, but I'm not sure what I should use in my dd command since I'm not positive about how much space is exactly before the 1st partition...
fdisk Output:
I read on a site that you can just divide the "Start" number in half to get Kilobytes (*which means there is 1MB before the 1st partition), but I'm not positive if that is accurate or not..?
What should I use as my dd command if I want everything BEFORE the first start'ing sector at 2048 (*i.e. before the 1st partition)?
Something like this?
If any has any thoughts or suggestions it would be much appreciated.
first of all, sorry about my english...I´m a spanish newbie to this marvelous OS and i have just a couple of doubts...u know? :-)

Hi
I'm doing some resilience testing and need to write a script to consume all of the available disk space on a partition and then to free it up again.
This would need to be -

I have a RHEL 5.3 machine with the following partitions and free space:
Free space on the partitions
/ : 74GB
/boot : 81MB
/var : 73GB
/home : 37GB
/icat : 758MB
/opt : 1.5GB
Now is it possible to allot a free space of some other partitions to /opt? I want around 100 GB more space... (4 Replies)

efi(4) Kernel Interfaces Manual efi(4)NAME
efi - Extensible Firmware Interface description
DESCRIPTION
The EFI (Extensible Firmware Interface) is an interface between HP-UX and the Itanium-based platform firmware. The file system supported
by the Extensible Firmware Interface is based on the FAT file system. EFI encompasses the use of FAT-32 for a system partition, and FAT-12
or FAT-16 for removable media. The system partition is required on a bootable disk for the Itanium-based platform.
For a hard disk, the system partition is a contiguous grouping of sectors on the disk, where the starting sector and size are defined by
the EFI partition table, which resides on the second logical block of the hard disk, and/or by the Master Boot Record (MBR), which resides
on the first sector of the hard disk. For a floppy disk, a partition is defined to be the entire disk.
The System Partition can contain directories, data files, and EFI Images. The EFI system firmware may search the directory of the EFI sys-
tem partition, EFI volume, to find possible EFI Images that can be loaded. The HP-UX bootloader is one example of an EFI Image.
HP-UX contains a set of EFI utilities:
efi_fsinit(1M) Initialize an EFI volume; that is, create a header and an empty directory.
efi_cp(1M) Copy files to and from an EFI volume.
efi_mkdir(1M) Create directories in an EFI volume.
efi_ls(1M) List the contents of an EFI volume.
efi_rm(1M) Remove files from an EFI volume.
efi_rmdir(1M) Remove directories from an EFI volume.
The EFI utilities are the only utilities in HP-UX where the internal structure of an EFI volume is known. To the rest of HP-UX, an EFI
system partition is simply a partition containing unspecified data. The EFI volume cannot be mounted to HP-UX currently.
An EFI volume can be created on any HP-UX file (either regular disk file or device special file) that supports random access via lseek(2).
Within an EFI volume, individual files and directories are identified by 1- to 255-character file names. File names can consist of any
alphanumeric characters (A through Z, a through z, and 0 through 9) and the certain set of special characters (. $ % ' - _ @ ~ ` ! ( ) + ,
: ; = # & ? ^ [ ] { } space). The first character of an EFI file name can be any valid EFI characters, except the space. When comparing
two EFI names, differences in the case of alphabetic characters are not significant. For example, the following file names are considered
the same:
If one exists, the user will not be able to create the other.
The directory may be made up of multiple components, separated by slashes(/). The last directory component must be followed by a slash to
separate it from the file name. There are two special directory components, (.) and (..). They represent the current directory and the
parent directory as in other file systems.
