!!!!! *YOU* *MUST* read the last paragraph about problems !!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!! Don`t wonder about the new size of the Updates and that !!!!!
!!!!! the Updater doesn`t print all module versions anymore. !!!!!
!!!!! This is NO bug. The modules are still there. !!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
New Upgrade features:
o Manual Mount support to allow the controller to search for
a RDB on units with a CDROM type like DVD Rams.
o CVPPC 31khz support..this is no real monitor but more a
copy gfxdata patch so it`s not that fast but still usable.
The native aga output is still there.
With older CGFX versions you may experience problems if
you boot with "echo on" or the shell window pop up.
Try to avoid anything in the startup-sequence which accidently
opens a screen before the Workbench.
o ECS/AA 31khz support
the Bootmenu now ALWAYS pops up in 31khz mode, so
people with 15khz monitors have to use <SPACE> to
switch the resolution to 15khz INTERLACE.
The resolution is saved too in the flash so the next
time it uses the resolution you set.
The resolution switch is disabled if there`s a permedia
card found.
o WideTermination check
A lot people don`t seem to have read the manual correctly
and use Wide/Narrow bridges without upper Widebus termination
which leads to not working reselection.
(Syndrom: 44.2 works perfectly with your devices but only slowly)
If the check detects such broken SCSI configuration the device
completely disables reselection for all units.
(CDROM is reselection by default)
ATTENTION:
Correct Termination checks are NOT 100%.
o New Unit ID standard so it works with WIDE HDs.
Board * 10*1000*1000
Lun * 10*1000
Unit * 10
+ 8 (8 in the last digit switches the format)
so if you wanna access Unit 13 Lun 5 it would look like
500138
or Unit 8 Lun 0
88
or Unit 1 Lun 0
18 (NewStyle)
or
1 (OldStyle)
The old Format was
Board * 100
Lun * 10
Unit * 1
so you could only use 9 Units though Wide provides 15.
I know the use of Unit=8 as a flag isn`t
elegant but it`s the only compatible system i found and
it`s not really that bad.
o Key "2" disables the processor on an 1200 ONLY.
o Key "s" pressed during booting disables the SCSI,
cdrive, bootmenu, bootmenu settings.
o Key "c" pressed during booting disables 31khz bootmonitor
and cvppc support
o Key "m" pressed during booting disables the memory
o Key "a" pressed during booting disables all
o BootMenu which can be invoked by holding
the Key <ESC> key during the system boot.
(It may not work for weird tower pc-keyboard hacks)
Then you see a menu with the 3 entries
o SCSI
o List with 8 or 16(WideSCSI) Units.
The entries show the current settings for the UnitID.
The Controller UnitID entry is marked differently.
If you click on the UnitID you get into a simular menu
like Unitcontrol`s Option menu.
If you click on the controller UnitID entry you get into
a simular menu like Unitcontrol`s Prefs menu.
Unit prefs:
o NO LUN
1 LUN
2 LUNs
3 LUNs
4 LUNs
5 LUNs
6 LUNs
7 LUNs
8 LUNs
-> This Entry can be used to disable the scan for the whole
unit for more Luns which can speed up booting a lot.
o Offset
Here you specify the synchron handshake.
o Period
Here you specify the synchron clock.
o ASynchron/Synchron
ASynchron
Synchron
Here you enable the synchron mode, so you
can change Offset and Period now.
The ASynchron/Synchron mode means that the
synchron mode is activated if specified by
the RDB for example.(The AUTO mode)
o Auto Buswidth
8-Bit
16-Bit
Here you specify the buswidth for a unit.
Well..anything more than Auto Mode isn`t really
needed.
o Auto Reselection
No Reselection
Reselection
Disabling reselection for units with problems is
possible here. Auto Mode means that reselection
is activated if the RDB flag is set or if it has
no RDB but is a normal unit like a cdrom.
Scanners and other esotheric units don`t use
reselection in AUTO mode.
o Auto Mount
Mount
No Mount
Auto Mount(normal) only searches RDB on random access and optical drives.
DVD Rams use the CDROM type and if the controller should search for a
RDB here you have to use "Mount".
o Auto Removable
Removable
No Removable
Only for completeness..
o CDBoot Pri
define the cdrom boot priority. Check the System Bootmenu for
the boot priority of other devices.
o CDRom Device Name
define the device name with which the cdrom should be mounted.
o No CDRom Bount
CDRom Mount
CDRom Boot
The buildin CDRom filesystem is the old Phase5 CDRive filesystem.
Its feature set may not be enough for your needs.
Controller Prefs:
o BusID
Controller BusID..normally 7.
The BusID of the controller. This doesn`t mean you
can use SCSI Nets as these don`t work in general.
o SCSIResetDelay
The seconds the device waits after the first
SCSI Reset/Init.
o ErrorDelay
The seconds the device waits after an Inquiry Error
o RemovableDelay
The second intervall for a removable check
o ErrorDelayRetry
The retry count for an Inquiry after an Error.
o ErrorRetry
The retry count for an SCSI Operation after an SCSI Error.
o TimeOut
(not yet used)
o CDFS
o No CDFS HD RDB Scan
CDFS HD RDB Scan
Update the filesystem.resource with CDFS filesystems when these
are placed in the RDB of HDs **BEFORE** the CD Drive at the same
controller. This way you can theoretically use other cdfilesystems.
*Theoretically* means that i haven`t tested if other cd filesystem
work with such startup as they may need to find their prefs.
The CDFS dostype is
#define ID_CDFS_DISK (0x43444653L) /* 'CDFS' */
The new SCSIConfig has an automatic filesystem entry for this.
o Cache Sets
How many Cache Sets are allocated.
CacheSets*CacheSetBlocks*2048 is the memory needed.
Only useful for CDFS
o Cache Set Blocks
The number of of each cache set.
A cache set is the line of block at Sector & ~(CacheSetBlocks-1) which
is fetched into the cache.
Only useful for CDFS
o RAM
Read SetMemMode documentation in the 68060 archive.
o MemorySpeed 70ns
-> standard waitstates
MemorySpeed 60ns
-> for 50Mhz 060 / 66Mhz PowerPC cards this means
o 68k No Read Waitstate
o 68k No Write Waitstate
o PPC No Read Waitstate
o PPC No Write Waitstate
Free Config
o 68k Read Waitstate
68k No Read Waitstate
-> possible with at least 70ns rams
o 68k Write Waitstate
68k No Write Waitstate
-> possible with at least 70ns rams
o 68k PreCharge
68k No PreCharge
possible with at least 60ns rams but not guranteed
to work with every ram.
(Enabled only for boards supporting this)
o PPC Read Waitstate
PPC No Read Waitstate
possible with at least 60ns rams
o PPC Write Waitstate
PPC
