14. rive or a CF card which are ATA devices and to access CD ROM or ZIP drive which are ATAPI devices you have to load additional third party software The general requirements to use the IDE Plus Interface are as follows a standard Atari XL or XE computer equipped with the PBI or Enhanced Cartridge Interface ECI connector Also more than 64k RAM is recommended a floppy disk drive this is only required for installation an IDE hard drive compliant to ATA 3 or later standard The latter means that the drive has to understand the so called LBA addressing If the drive is produced in 1996 or earlier it probably does not Utilities tools and the system software is being maintained actively and continuously developed Software updates can be downloaded from the following URL http drac030 krap pl en kmkjz pliki php We would like to thank Larry White for many useful suggestions he had about this manual I Preliminary information The Interface s internal software or BIOS provides two modes of operation native mode and emulation mode The native mode uses a 512 byte physical block as a logical data sector the emulation mode uses the physical block to store one 128 or 256 byte logical data sector Almost all existing DOSes require the emulation mode to work properly and limit the partition size to 16 MB The only one DOS which can do sectors greater than 256 bytes and is therefore capable of taking a
15. the XE series has been produced with rubber legs being a bit higher As a result the interface plugged into the CART ECI connector is not plugged correctly but it hangs down from the connector consequently a part of the connector pins do not stick well The solution is to insert a 2 3 mm pad under the interface or provide a cable connection
16. three questions 1 Chip erase if it should clear the BIOS ROM Answer Y 2 Chip write if it should rewrite the BIOS with new contents Answer Y unless you are doing some experiments and want to leave the ROM cleared 3 Exit to DOS Answer Y if you want to exit or N if you want to restart the updating process After the last step is completed it is a good idea to power the machine down for a while to make sure that the new BIOS is initialized totally anew Note that an ordinary Cold Reset does not ensure that IV Write protection The IDE Plus 2 0 interface provides the write protection feature to minimize a risk of accidental data damage caused by viruses damaged software or children When a partition is write locked there is NO POSSIBILITY to write data to that partition or unlock it by executing commands causing a cold boot or turning the power off and on Also damaging a write protected partition by writing accidental data to random memory locations is practically impossible You can mark a partition write protected using the Lock option Control L in FDISK2 V Executing non DOS software with the hard drive Some software especially games and demos have their own disk formats and cannot be copied to a partition However the firmware provides limited ability to execute such programs If your BOOT partition is not the D1 you may run a non DOS disk from the
