Operating Manual of the PC. Problems can occur with programs in which time loops have been implemented The lithium battery on the board may only be replaced by specialist through software loops. This applies in particular to older programs which were technicians. There is a danger of explosion if this is not done properly. written for 8 MHz processors. The lithium battery must be replaced with an identical battery or a battery type recommended by the manufacturer. The lithium battery must be disposed of in accordance with local regulations SCO-UNIX on devices with processor i486 DX2 or OverDrive on the disposal of special refuse. If you upgrade the system board by adding a processor mentioned above, please Be sure to read this page carefully and note the information before you note the following: open the PC. If you use the processor mentioned above, the Adaptec-SCSI controller cannot be addressed under SCO-UNIX 3.2.4 and ODT 2.0. Modules with electrostatic sensitive devices (ESD) may be identified by labels. To solve this problem, you can order from SCO a set of SLS (Support Level Supplement) floppies (consisting of 3 floppy disks) under the number uod361, free of charge, or contact SNI's spare parts service. The problem no longer exists in the new releases of SCO-UNIX 3.2.4.2 and ODT 2.1. There will be no support for older versions (SCO-UNIX versions lower than 3.2.4 and ODT versions lower than 2.0). When you handle modules fitted with ESDs, you must observe the following points under all circumstances: – When you handle modules fitted with ESDs, you must always discharge yourself (e.g. by touching a grounded object) before working. – The equipment and tools you use must be free of static charges. – Pull out the power plug before inserting or pulling out modules containing ESDs. – Always hold modules with ESDs by their edges. – Never touch pins or conductors on modules fitted with ESDs.
