0.91 beta project page
Welcome to the home of the IDE Disk Operating System 0.91 for the IDE64 cartridge!
The next version of IDEDOS is coming, but it needs some more time to
be finished. But this does not mean that there are no interesting
features which can be tried out until it's fully finished. Also I'd like
to know if the finished parts work as expected, or if there are some old
features which do not work anymore. But as always:
This IDEDOS 0.91 beta release is not very well tested and could destroy your data!
Which is of course not the intention, but having good backups is a very
good idea if there's something important stored on the disks. The point
of the release is to get more testing on diverse hardware and to get feedback.
IDEDOS changes since 0.90 20091029, which are done:
- OFS 0.02 support removed
- The old filesystem used by IDEDOS 0.89x is not supported anymore, as
this is only taking up space and probably everyone has converted by now.
- Protected BASIC, serial and PCLink routines.
- There was an incompatibility with interrupt routines located in the
ROM banking area when the BASIC extension, serial and PCLink routines
were running, which caused crashes for some software. This should be no
problem anymore on C64. (but this problem still exists on SuperCPU due
to hardware limitation)
- F-keys work with interrupts
- Setting up a custom interrupt routine automatically disabled the hotkey
support. This should not happen anymore, as this was a workaround.
- Read ($DEF4) works under I/O
- This allows faster disk operations in the monitor when loading under
the I/O area, but can be used by user software as well. Probably some of the
picture plugins will be updated to use this.
- PCLink load below I/O works now
- Loading huge programs over PCLink should be no problem now. This was
already a standard feature for IEC and normal IDEDOS drives.
- SilverSurfer PCLink support, PCLink optional
- In theory this should be possible now, but it was not tested on
real hardware yet. Also now it's possible to completely disable PCLink support.
- FAT filesystem read ($DEF4) and load
- Now copying is much faster from a FAT volume, and loading files also
works now. Probably this will increase the confusion of new people who
forget to format a drive to native CFS and want to write to it, as
everything seems to work except writing.
- Combined CFS and FAT partitions, per partition filesystem support
- Now if there are FAT partitions on a disk which has a CFS partition
table then the FAT partitions are not hidden anymore, but are filling up
the unused CFS partition entries in the CFS partition table as foreign
partitions. To make this useful the limit of one filesystem type per
drive is removed now and the filesystem type belongs to the partitions,
like it should be normally. FAT partitions take up twice the space so
there can be at most 8 if there are no CFS partitions.
- Partition list for FAT and ISO9660
- The partition list is automatically generated for FAT and ISO9660
volumes, so it's not an error anymore when there's no CFS partition
table on disk.
- Dynamic drive enumeration, PCLink detection
- The drive numbers are not hardcoded now (e.g. drive 1→primary
slave), but are assigned in the order of detection. Also PCLink drives
disappear when there's no hardware connected (e.g. no network card
connected, but support is compiled in). 5 drives are supported, but only 4
of them can be a normal drive, the 5th can only be PCLink.
- Read ($DEF4) and write ($DEF1) support on modifiable files
- IDEDOS 0.90 only allowed character I/O on modifiable files, but this
limitation was fixed now. This opens up possibilities to create high
performance database software, read/write image file support (D64) or
IFFL system with fast read/write support.
- Timestamp update only if modified
- The timestamp is only updated if the modifiable file was really
modified, a simple open and reading is no reason for a timestamp update.
- Seeking, modifiable and appendable files on PCLink
- The PCLink drive gained standard features of normal IDEDOS drives.
So now it should be possible to enter D64 files on PCLink too, or play
Maniac Mansion over the network.
- PCLink protocol changes
- This was necessary due to seeking, and performance reasons. With the
new protocol USB PCLink is ~55 KB/s for both read and write, and
the Ethernet PCLink is at ~60 KB/s in both directions (with SuperCPU it's 200 KB/s!).
Unfortunately an updated ideserv is necessary, but Rush can be played
over EPCLink now with proper frame rate.
- Drive types
- The internal architecture was reworked to understand drive types
beyond ATA and ATAPI, for example PCLink is one of the new drive types now.
This is an important change, but I guess it's not very interesting for
- PCLink activity LED
- The extra LED on the V4.1 cartridge is now used as PCLink activity
LED. Before it was the error led, but it had a lot of quirks. (there was
no way to tell which device was in fault, and if more than one was in
fault, then sometimes it was not shown)
- Additional editor function keys
- In 0.90 the only function key was CONTROL+D. Now there are some more to move
the cursor around, clear parts of line or toggle repeat/insert mode.
- Floppy speeder cleanup
- Now 1581 has fastsave support, and 1571 native mode is supported as well.
Also fastsave is not limited to the manager anymore, it's also used by the
SAVE KERNAL call.
IDEDOS changes since 0.90 20090702, which are to do:
- Relative files
- Due to internal changes the relative file support is broken temporary.
- Executable flag on files
- It's ignored for now due to internal changes, future is uncertain.
- SuperCPU support
- Could be broken at some places, as not much testing was done yet.
- Some things could be broken, which already worked on IDEDOS 0.90 and are
not on this list. Please help to find them.
Please send your experiences to the IDE64 mailing list, which is now at:
- Initial upload
- PCLink could delay the boot quite a lot in some cases, fixed now.
- PC64 frame error fixes, and PCLink+CRC compile failure fix.
- All PCLinks except Ethernet corrupted a byte in RAM around ~$b300
during read because of a typing mistake.
- If only write were used with special size to write a file then it
could happen that the file was not marked as modified which
prevented proper close.
- The SuperCPU version does not crash on boot anymore and is now testable.
- Error LED on V4.1 is now PCLink LED.
- KERNAL file table emulation
- KERNAL file table use for normal operation. No double channel use anymore,
10 open files only, but ACE works now ;)
- Load allows to load to $2a7-$2ff now from IDEDOS devices.
- Directory load below I/O is supported now, verify failing works over pclink.
- Wrong data was written if the buffer had to be flushed first in blockwrite.
- Blockread after last byte of sector position increment bug
