So, usually one will want a second Linux partition +dedicated as swap partition. +On Intel compatible hardware, the BIOS that boots the system +can often only access the first 1024 cylinders of the disk. +For this reason people with large disks often create a third partition, +just a few MB large, typically mounted on +.IR /boot , +to store the kernel image and a few auxiliary files needed at boot time, +so as to make sure that this stuff is accessible to the BIOS. +There may be reasons of security, ease of administration and backup, +or testing, to use more than the minimum number of partitions. + +.B pmac-fdisk +(in the first form of invocation) +is a menu driven program for creation and manipulation of +partition tables. +It understands DOS type partition tables and BSD or SUN type disklabels. + +The +.I device +is usually one of the following: +.br +.nf +.RS +/dev/hda +/dev/hdb +/dev/sda +/dev/sdb +.RE +.fi +(/dev/hd[a-h] for IDE disks, /dev/sd[a-p] for SCSI disks). +A device name refers to the entire disk. + +The +.I partition +is a +.I device +name followed by a partition number. For example, +.B /dev/hda1 +is the first partition on the first IDE hard disk in the system. +IDE disks can have up to 63 partitions, SCSI disks up to 15. +See also +.IR /usr/src/linux/Documentation/devices.txt . + +A BSD/SUN type disklabel can describe 8 partitions, +the third of which should be a `whole disk' partition. +Do not start a partition that actually uses its first sector +(like a swap partition) at cylinder 0, since that will +destroy the disklabel. + +An IRIX/SGI type disklabel can describe 16 partitions, +the eleventh of which should be an entire `volume' partition, +while the ninth should be labeled `volume header'. +The volume header will also cover the partition table, i.e., +it starts at block zero and extends by default over five cylinders. +The remaining space in the volume header may be used by header +directory entries. No partitions may overlap with the volume header. +Also do not change its type and make some file system on it, since +you will lose the partition table. Use this type of label only when +working with Linux on IRIX/SGI machines or IRIX/SGI disks under Linux. + +A DOS type partition table can describe an unlimited number +of partitions. In sector 0 there is room for the description +of 4 partitions (called `primary'). One of these may be an +extended partition; this is a box holding logical partitions, +with descriptors found in a linked list of sectors, each +preceding the corresponding logical partitions. +The four primary partitions, present or not, get numbers 1-4. +Logical partitions start numbering from 5. + +In a DOS type partition table the starting offset and the size +of each partition is stored in two ways: as an absolute number +of sectors (given in 32 bits) and as a Cylinders/Heads/Sectors +triple (given in 10+8+6 bits). The former is OK - with 512-byte +sectors this will work up to 2 TB. The latter has two different +problems. First of all, these C/H/S fields can be filled only +when the number of heads and the number of sectors per track +are known. Secondly, even if we know what these numbers should be, +the 24 bits that are available do not suffice. +DOS uses C/H/S only, Windows uses both, Linux never uses C/H/S. + +If possible, +.B pmac-fdisk +will obtain the disk geometry automatically. This is not +necessarily the physical disk geometry (indeed, modern disks do not +really have anything like a physical geometry, certainly not something +that can be described in simplistic Cylinders/Heads/Sectors form), +but is the disk geometry that MS-DOS uses for the partition table. + +Usually all goes well by default, and there are no problems if +Linux is the only system on the disk. However, if the disk has +to be shared with other operating systems, it is often a good idea +to let an fdisk from another operating system make at least one +partition. When Linux boots it looks at the partition table, and +tries to deduce what (fake) geometry is required for good +cooperation with other systems. + +Whenever a partition table is printed out, a consistency check is performed +on the partition table entries. This check verifies that the physical and +logical start and end points are identical, and that the partition starts +and ends on a cylinder boundary (except for the first partition). + +Some versions of MS-DOS create a first partition which does not begin +on a cylinder boundary, but on sector 2 of the first cylinder. +Partitions beginning in cylinder 1 cannot begin on a cylinder boundary, but +this is unlikely to cause difficulty unless you have OS/2 on your machine. + +A sync() and a BLKRRPART ioctl() (reread partition table from disk) +are performed before exiting when the partition table has been updated. +Long ago it used to be necessary to reboot after the use of pmac-fdisk. +I do not think this is the case anymore - indeed, rebooting too quickly +might cause loss of not-yet-written data. Note that both the kernel +and the disk hardware may buffer data. + +.SH "DOS 6.x WARNING" + +The DOS 6.x FORMAT command looks for some information in the first +sector of the data area of the partition, and treats this information +as more reliable than the information in the partition table. DOS +FORMAT expects DOS FDISK to clear the first 512 bytes of the data area +of a partition whenever a size change occurs. DOS FORMAT will look at +this extra information even if the /U flag is given -- we consider +this a bug in DOS FORMAT and DOS FDISK. + +The bottom line is that if you use pmac-fdisk to change the size of a +DOS partition table entry, then you must also use +.B dd +to zero the first 512 bytes of that partition before using DOS FORMAT to +format the partition. For example, if you were using pmac-fdisk to make a +DOS partition table entry for /dev/hda1, then (after exiting pmac-fdisk +and rebooting Linux so that the partition table information is valid) you +would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero +the first 512 bytes of the partition. + +.B BE EXTREMELY CAREFUL +if you use the +.B dd +command, since a small typo can make all of the data on your disk useless. + +For best results, you should always use an OS-specific partition table +program. For example, you should make DOS partitions with the DOS FDISK +program and Linux partitions with the Linux pmac-fdisk program. + +.SH OPTIONS +.TP +.B \-v +Print version number of +.B pmac-fdisk +program and exit. +.TP +.B \-l +List the partition tables for +.BR /dev/hd[a-d] , +.BR /dev/sd[a-h] , +and then exit. +.TP +.B \-u +When listing partition tables, give sizes in sectors instead +of cylinders. +.TP +.BI "\-s " partition +The +.I size +of the partition (in blocks) is printed on the standard output. +.SH BUGS +There are several *fdisk programs around. +Each has its problems and strengths. +Try them in the order +.BR cfdisk , +.BR pmac-fdisk , +.BR sfdisk . +(Indeed, +.B cfdisk +is a beautiful program that has strict requirements on +the partition tables it accepts, and produces high quality partition +tables.

The +.B i +and +.B w +commands will prompt for confirmation. None of the editing you do will +actually affect the state of the disk you are partitioning until the +.B w +command is issued. Then the map in its edited state will be +permanently written to the disk. + +Partitions are always specified by their number, the index of the +partition entry in the partition map. Many commands will change the +index numbers of partitions which follow the affected partition; you are +encouraged to use the +.B p +command to print the partition table as frequently as necessary. For SCSI +disks, the partition table should not contain more than fifteen partitions +(partition map excluded).

You can just +type Return to accept the offered size, which should be correct. + +The +.B b +command is a shortcut to create the bootstrap partition used on PowerPC +NewWorld machines. It is equivalent to creating an 800k +.B Apple_Bootstrap +type partition using the +.B C +command described below. The sole purpose of this partition is to +store the boot loader. In multiboot environments, the first bootable +partition found on the disk takes precedence unless a specific boot +partition is set in OpenFirmware, so it's best to create the bootstrap +partition first, or move it to a position before any +.B Apple_HFS +or +.B Apple_Boot +partitions using the +.B r +command described below. Then you will still able to boot Linux after +the occasional OpenFirmware reset. + +The +.B c +(create new partition) command has three arguments. As mentioned +above you can type the arguments following the command, separated by +spaces, or respond to prompts for each argument: + + 1) The base address of the start of the partition. + + You can specify a number in blocks (most likely reading from the + existing partition map) or you can also type a partition number + followed by the letter 'p' to indicate that the new partition + should take the place of that existing free space partition. + + 2) The length of the partition. + + Again, you can specify a number in blocks or type a partition + number followed by the letter 'p' to indicate use of the entire + partition. You can also type a number followed by 'k', 'm', or + 'g' to indicate the size in kilobytes, megabytes, or gigabytes + respectively. (These are powers of 1024, of course, not powers + of 1000.) + + 3) The name of the partition. + + This can be a single word without quotes, or a string surrounded + by single or double quotes. It is best to name any swap partition + you create `swap'; other partition names are up to you. The names + are not visible to Linux. + +The +.B C +command is identical to the +.B c +command, with the addition of a partition type argument after the +other arguments. The partition type used for Linux swap and data partitons +is +.B APPLE_UNIX_SVR2 +(this is the partition type created by the +.B c +command). Under normal circumstances, you should not need to use this +command. + +The +.B d +command deletes the partition number specified, replacing that partition +with partitionable free space. + +The +.B r +(reorder) command allows the index number of partitions to be changed. +The index numbers are constrained to be a contiguous sequence. +.B mac-fdisk +will enforce this constraint by recalculating the partition numbers +after each insert, delete or reorder operation. OpenFirmware looks for +bootable partitions in the order specified by the index. The +partitions are not moved on the disk. This command takes two +arguments, the number of the partition to be moved and the partition +number it should become. + +The +.B w +command writes the partition map out to disk. Note that partition +maps for disks with mounted partitions cannot immediately be +reinterpreted by the kernel. In order to use the new partition map you +must reboot. Within the Debian installer system, +.B mac-fdisk +is normally invoked before any partitions are mounted, thus a reboot is not +necessary before continuing the installation. + +The +.B q +command terminates the program. If there was no +.B w +command issued during the program run, then there will be no effect on the disk. + +.SH BUGS +Some people believe there should really be just one disk partitioning utility. + +.B mac-fdisk +should be able to create HFS partitions that work. Currently, if a +pre-existing HFS partition is resized, MacOS will continue to use the +partition size stored in the HFS 'superblock' instead of using the size from +the partition table (the MacOS volume on the partition remains valid even +though the sizes don't match anymore). This can have undesired side effects +especially when creating a smaller HFS partition followed by a few Linux +partitions in place of the previous HFS partition space. To avoid this +issue, create MacOS partitions within MacOS and then don't resize them +in +.B mac-fdisk. + +.SH "SEE ALSO" +.BR fdisk (8), +.BR mkswap (8), +.BR mkfs (8) +.SH AUTHOR +Eryk Vershen (eryk@apple.com), man page revised by Chris Tillman (tillman@azstarnet.com) --- mac-fdisk-0.1.orig/io.c +++ mac-fdisk-0.1/io.c @@ -30,6 +30,10 @@ #include <stdlib.h> #include <fcntl.h> #include <SCSI.h> +#else +#ifdef __GLIBC__ +#include <sys/types.h> +#endif #endif #include <unistd.h> #include <string.h> @@ -51,6 +55,8 @@ #define SCSI_FD 8 #define loff_t long #define llseek lseek +#else +#define llseek lseek64 #endif @@ -435,8 +441,8 @@ #else { #endif - x = num * PBLOCK_SIZE;
