<H1 ALIGN="CENTER">IDEDOS - the access to harddisks</H1>
<P>The IDEDOS means extra facilities of the +3e operating system,
written by Garry Lancaster. For more details please consult his
page at <A HREF="http://www.zxplus3e.plus.com/">http://www.zxplus3e.plus.com/</A>.
<P>In ZXVGS and CPM22QED is implemented the IDEDOS partition table
(also called IDEDOS system partition).
<P>Searching for IDEDOS structures:
<OL>
<LI>Read the sector 1 on cylinder 0 and head 0.
<LI>If sector length is 512B (full IDE), go to 5.
<LI>(Simple IDE - sector length is 256B.) If "PLUSIDEDOS" signature found, go to 10.
<LI>Don't mount the disk at all.
<LI>If "PLUSIDEDOS" signature found, go to 10.
<LI>If "P?L?U?S?I?D?E?D?O?S" signature found, switch disk
access to 8-bit and go to 10.
<LI>Read the sector 1 on cylinder 0 and head 1.
<LI>If "PLUSIDEDOS" signature found, go to 10.
<LI>Don't mount the disk. (Or try to analyse MS-DOS
partition tables.)
<LI>Analyse IDEDOS partition table.

<TH ALIGN=CENTER>Description
<TR>
<TD ALIGN=CENTER>#00
<TD>Unused partition/free handle.
<TR>
<TD ALIGN=CENTER>#01
<TD>System partition. The first partition on a disk, starting at phisical
sector 1 (cylinder 0, head 0 or 1), is always the system partition and
contains a list of 64-byte
partition entries that define all the partitions on the disk (including
the system one). Only one partition of this type is
permitted on a disk, and this is always the first partition. The name
is always "PLUSIDEDOS" (followed by 6 spaces).
<TR>
<TD ALIGN=CENTER>#02
<TD>Swap partition.
<TR>
<TD ALIGN=CENTER>#03
<TD>+3DOS partition. The maximum theoretical size for a +3DOS
partition is just under 32Mb. The XDPB has logical geometry.
<TR>
<TD ALIGN=CENTER>#04
<TD>CP/M partition with XDPB that reflects phisical
disk structure. So if the disk has 17 spt, the LSPT is
68. The partition uses always integer number of
cylinders and uses whole cylinder (from head 0).
Otherwise (when from not track 0) this is converted to
reserved tracks (OFF in XDPB). This is required for my
DSKHNDLR low level disk drivers.
<TR>
<TD ALIGN=CENTER>#05
<TD>Boot partition. This is only one file, stored
as a partition. Used to boot a hardware. Eg. Timex FDD 3000
extedend with YABUS.TF, will search the IDEDOS partiton
table to find "YABUS.TF" partition. If found, the partition
contents is loaded into RAM and started. The partition size
is usually 8k to 64kB, what gives 1..2 tracks (or 1..8 track
for disks with 17 spt). The number of sectors to load is in
partition definition.
<TR>
<TD ALIGN=CENTER>#10
<TD>MS-DOS (FAT16) partition.
<TR>
<TD ALIGN=CENTER>#20
<TD>UZI(X) partition.
<TR>
<TD ALIGN=CENTER>#30
<TD>TR-DOS diskimage partition. Usually 640kB. Sector offset.
<TR>
<TD ALIGN=CENTER>#31
<TD>SAMDOS diskimage partition (B-DOS record), 800kB. Sector offset.
<TR>
<TD ALIGN=CENTER>#32
<TD>MB-02 diskimage partition. Usually 1804kB. Sector offset.
<TR>
<TD ALIGN=CENTER>#FE
<TD>Bad disk space.
<TR>
<TD ALIGN=CENTER>#FF
<TD>Free disk space.

<H2>Example partitions data</H2>
<P>The disk is Seagate ST351A/X and its structure is 980/5/17 (not the
reported in manual 820/6/17).
<P>First track is reserved to allow MBR and MS-DOS partitions table in
0/0/1 sector. The MS-DOS (and other) partitions can start at cylinder
198 as IDEDOS structure ends at cylinder 197 inclusive. IDEDOS structure
could also take whole disk and contain MS-DOS partition inside.
<P>IDEDOS structure starts at sector 0/1/1, so 1 * 17 * 512 = 8704 = #2200
bytes are skpipped.<BR>

</PRE>IDEDOS system partition (type #01 - area that describes other partitions).
Starts at cylinder 0 head 1 and ends at the same one.
Partition size is 11 sectors (#00000010).
At #02220 disk parameters are defined: 198 cylinders (#0C6, two bytes),
5 heads (one byte), 17 sectors per track (#11, one byte), sectors
per cylinder is calculated to 85 (#0055, two bytes). Up to 136
partitions can be defined (#0087 is last number = 1 * 17 * 512 / 64 - 1, two
bytes). Area behind from cylinder 198 is reserved for other systems
(e.g. MS-DOS) and not available as IDEDOS partitions.
