IBM PC330/PC350 - 3278/9 adapter not found or 28xx diagnostics error
Applicable to: World-Wide
Symptom:
IBM PC 300 Series 6576 and 6586 may display an "Adapter Not Found" error using a communication application or POST a "2810 S" error when running the 3278/79 Emulation Adapter Diagnostics.
Problem Isolation Guidance:
The 3278/79 Emulation adapter requires specific system resources to operate correctly. The 3278/79 adapter must utilize IRQ 2 and an 8kb memory page - usually at address "CE00." The 6576/86 systems default configuration has the "CE00" area shadowed so the adapter will not be seen.
Fix:
The memory address at "CE00" must be made available to the 3278/79 Emulation adapter by using the following procedure:
1) Access the PC 300 Setup Utility by pressing F1 during the memory count.
2) Select Advanced Setup
3) Select ROM Shadowing
4) Disable the ROM Shadowing in the CC000h-CFFFFh area.
5) Save/Exit the Setup Utility and allow the system to reboot.
If the error persists, continue normal problem determination procedures.
NOTE:
The CE00-CFFF adapter address can be reconfigured by some PC/3270 Emulation software products.
