Problems and Solutions
How do I assign an interrupt for the host adapter?
The interrupt assignment is handled via the motherboard BIOS. You
may or may not be able to assign an interrupt manually. Refer to
your motherboard or system documentation.
During installation, OS/2 fails to find the hard drive.
Make sure the latest driver from Adaptec has been installed. Add
the /pcihw or /!pcihw command option to the basedev=aic7870.add
(or
aic78u2.add ) driver statement in the config.sys file.
Does extended translation need to be enabled on the host adapter to support drives
greater than 1GByte?
Under OS/2, if you are using a FAT file system and/or switching
back and forth from DOS, extended translation should be enabled. If
you are using HPFS (High Performance File System), extended
translation may or may not be enabled. Once the driver for the host
adapter loads, the remaining hard drive space will be seen beyond
1024KBytes.
