************************************ New Features for the v 5.0 upgrade: ************************************* 1. Full support for the Atari XF551 disk drive, including Double sided/Double density and high speed transfer. 2. Complete XF551 compatibility with previous disk drives. double density drives can read files on Double sided disk (just as single density drives can read Enhanced density disk). 3. High speed transfer and skewed sectors for US Doubler, XF551 and SUPERMAX. 4. Full sector count displayed, no more 999+. 5. Full support for Newell 256K memory upgrade for 800XL. 6. Hold down [Esc] during boot up to reserve the 130XE memory banks for your program. 256K and 320k computers can use BASIC XE and a RAMdisk. 7. Bug in RAMdisk reboot (coldstart) routine fixed. 8. The right margin is no longer set to 37. Using SUPERDOS with an XF551 The Atari XF551 disk drive is the first 2 sided/Double density available for the Atari computer. No standard for its disk format has emerged yet. DOS XE (when it appears) is not compatible with DOS 2.5 and 2.0. We think this is a fatal flaw and DOS XE will be rejected by the Atari community the same way incompatible DOS 3.0 was. SUPERDOS offers a compatible alternative. 2 sided/Double density is handled much the same way Enhanced density was. A normal 1 sided/Double density is set up and the it is extended. Files which are contained entirely on side one can be accessed normally by and Double density drive (i.e., US Doubler, Indus, SUPERMAX, RANA, ect.) Files which are wholly or partly on side two are bracked in the directory listing and can only be accessed by a sided/double density drive. Using SUPERDOS with RAMdisk A RAMdisk is a portion of memory configured to emlate a disk drive. The computer uses it like a drive. RAMdisk are much faster than Physical drives and are very convenient for many jobs. Note, However that the RAMdisk is erased when the comouter is turned off. Be sure to copy your RAMdisk contents to a physical disk before truning off your computer. SUPERDOS sets up a RAMDISK in the "extra" memory of the 130XE and most memory expansions. SUPERDOS supports Peterson, SUPERMAX, Mega, and Byrd 320 kbyte expansions for the 130XEs: Bucholtz, RAMbo, and Newell 256 kbyte expansions for the 800XLs: and Axlon 128 Kbyte expansions Byrd, Chu, Mega and other Axlon compatible 288K byte memory expansions in 800s and 400s. RAMdisk users are advised to make an extra "reboot" SUPERDOS disk. Use this extra disk to boot the compter without losing the contents of the ramdisk. It works like this: you can reboot your computer without turning it off with a coldstart switch modification or by POKEing 580,1 and then pressing [reset]. This reboot process does not erase the "extra" memory area and the contents of the RAMdisk are preserved. However when SUPERDOS loads, it automatically re-initializes the RAMdisk which erases it. Here's how to prevent that: from SUPERDOS load AUX.SYS Press X to turn RAMdisk enable off (O) Press P to re-initializes DOS. Press Z to return to SUPERDOS. Place a blank disk in your drive (initialize it if necessary) and press H to write DOS and SDUP to the blank disk. lable this new disk REBOOT SUPERDOS. Always place the REBOOT SUPERDOS disk in the drive one before doing a coldstart. the 5+ inicator in the status line will be blank, but as soon as you access the RAMdisk, it will be restored. Using SUPERDOS with an 800/400 SUPERDOS works fine with 800's and 400s (expanded to 48K). Since these computers do not have the extra 16 Kbytes of memory "under" the operating system, SUPERDOS can't store the SDUP there. If you have an Axlon compatible memory expansion, SUPERDOS will store the SDUP there. If you only have 48K bytes, you will have to decide how you want SUPERDOS to handle SDUP. You can have SDUP remain on disk, or you can make it "resident" at the bottom memory. If you leave SDUP on disk, it will free up more memory for your program, but will take some time to load if you need it. Additionally when it does load, it will overwrite some of the program area and destroy the data there. Be sure to save your materials before calling SDUP. If you make SDUP resident, you will have less memory for your program, but SDUP will be available instantly and it will not overwrite your program. It is recommended that you make two SUPERDOS disk, one with SDUP resident, one with it not resident. Here is how to do it: SUPERDOS is shipped with SDUP not resident. Make a copy of your master disk and label it SUPERDOS NOT RESIDENT. From SUPERDOS, load AUX.SYS Press Y to make SDUP resident. Press P to re-initialize SUPERDOS. Press Z to return to SUPERDOS. Put a blank disk in drive one (initialize it if necessary) and press H to write SUPERDOS and SDUP to the blank disk. Label this disk SUPERDOS RESIDENT. Boot your system with the appropriate disk for the job you want to do.

Some programs dont need you to have a US DUPLICATOR within your drive. Files on disk USDUP5 .COM Requires US DUPLICATOR. SKEWCOPY.COM Requires US DUPLICATOR and 'SKEW.DAT'. SKEW .DAT Data file for 'SKEWCOPY.COM'. MODCOPY .COM Sector copier for any drive. SECTCOPY.COM Sector copier for protected enhanced density disk, work on any drive? MKDEPDUP.COM Make a disk to de-program the US Duplicator. USFILE .COM Ultra-Speed file I/O, works on any drive, just run it or it may be appended in front of other executable DOS files. DISKTEST.COM Always use a blank disk as this one formats it. XECOPY .COM XE only. USDISK .COM Ultra-Speed disk I/O, works on any drive, this one locks up when loaded, press Start to reboot in Ultra-Speed for basic or for boot disk hold Option then press Start, but dont hold Start too long or you will get the bleep for loading tapes. REGRPM .BAS Standard RPM program for American drives. MODRPM .BAS Slow mode RPM program for American drives. EURRPM .BAS Standard RPM program for European drives. EUSRPM .BAS Slow mode RPM program for European drives. MENU . Menu for RPM Programs. README .DOC This file, written by ASI Industries. ******************************** Documentation for FASTLOAD.BAS ******************************** Documentation for FASTLOAD.BAS This utility adds ultraSpeed Skew to non-SpartaDOS disk such as DOS 2.5 and Rana SmartDOS. Run FASTLOAD.BAS from BASIC and follow the Prompts. Briefly, format a disk using SpartaDOS's XINIT.COM choosing NO DOS and any density. Then use a sector copier (such as SpartaDOS's SCOPY.COM) to copy the non-SpartaDOS disk to the freshly formatted disk. Then RUN FASTLOAD.BAS, which will write QUICK.OBJ to the sector copied disk, allowing it to run at UtraSpeed (when using a 1050 disk drive with ICD's U.S. Doublers). (PaperClip disks are also supported.) *************** HIGHSPEED SIO *************** - This COM file moves the OS from ROM to RAM and installs a high speed SIO. It allows any modified 1050 or XF551 (equipped with Happy, US Doubler, Speedy, Hyper-XF ect.) to run at high speed (three times faster than normal), without the must-use of any special DOS..... -This will only work on programs, That do not disturb bit 0 of location $D301 (Atariwriter, Micro Illustr., PM Animator, ABC Compiler, Chameleon, and almost all older programs). -To use SPDSIO1.COM, load it from your favourite DOS (excluding: DOS XE, Bibo-DOS, Sparta-DOS and others, that use RAM under ROM), using the binary load function. You can now load most files with high speed.... ******************* HIGHSPEED SIO II: ******************* - This COM file also moves the OS from the ROM to RAM and installs a high speed SIO routine. It allows any modified 1050 or XF551 (equipped with Happy, Speedy, US Doubler, Hyper-XF, ect.) to run at high speed (three times faster than normal) without the must-use of any special DOS.... -This too works merely on programs that do not disturb bit 0 of location $D301 (Atariwriter, Micro Illustr. PM Animator, ABC Compiler, Chameleon, and almost all older programs). -To use this file, put it on a work disk with DOS 2.x and rename it to AUTORUN.SYS. Boot the disk. The file will load and seem to hang - REMOVE the SPDSIO2 disk (it cannot load itself) and put in the boot-disk you want to boot with high speed... Use the OPTION key just as you would normaly + hit the Start key. The disk in drive 1 will boot at high speed and run normaly. Reset is not trapped and will kill SPDSIO2, but not your program - if it has its own restart routine...... -To futher increase the transfer rate of the disk files, or boot disk, the diskette should be formatted using sector skew. The fastest tranfer rate occurs with the 1050 medium/dual denity, even though most programs can't use all 1040 sectors.
