IBM OS/2

Known Issues

•This version of the Adaptec 7800 Family Manager Set v3.00 driver added a new switch named /!PCIHW which enables the driver to skip accessing the PCI hard- ware registers directly, and use PCI BIOS instead. This switch could be useful for users having problems loading the driver included with IBM OS/2 Warp or SMP. Modify the CONFIG.SYS file to include the following line:

a.For Ultra2SCSI host adapters: BASEDEV=AIC78U2.ADD /!PCIHW

b.For UltraSCSI or earlier host adapters: BASEDEV=AIC7870.ADD /!PCIHW

•Intel Errata #8511 lists known data integrity issues with the processor cache on the Saturn-1 chipset (82424TX).For this reason, Adaptec recommends that pro- cessor cache be disabled via the CMOS setup to avoid data corruption.For more information, see Intel Errata #8511.You may get this from Intel's FaxBack sys- tem at 800.628.2283 or 916.356.3105.For more detailed information see Errata #8512 and #8513.

•Can't install on the maximum hard disk drive partition size supported by IBM OS/2 v3.0. On IBM OS/2 v3.0 it is a known problem. Refer to IBM for further info. IBM's APARs PJ15988 and PJ 6151 deal with this issue.

Additional Notes

•This version of the Adaptec 7800 Family Manager Set v3.00 driver supports the AIC-7800 Family of Host Adapters.Adapter numbers are first assigned to boards with their BIOS enabled.The numbers are assigned from lowest BIOS address to highest address.Any remaining boards are assigned numbers by scanning slots.Each slot is a combination of a bus number and a device number pair start- ing from lowest to highest numbers, and the adapters are assigned a number in the order they are found.

Example:

Bus 0, device 0 assigned as adapter 0,

 

Bus 1, device 1 assigned as adapter 1, etc.
