Installation FAQ

My AHA154x/174x isn't being detected

On some machines which were fast for their time (e.g. 486DX2/66), the timeout in the kernel routine that initializes the card may run too quickly, causing the system to not be able to use your host adapter. SCO has a fixed version of /etc/conf/pack.d/ad/Driver.o that increases the timeout value; this should cure the problem. This fix (in unx365b for Unix 3.2v4.0 and 3.2v4.1, or oda366b for ODT 2.0) is available from SCO's usual channels (see the administrative FAQ for info on ftp and UUCP access). Later versions of the operating system include this fix; it is not applicable to anything earlier than 3.2v4.0 and ODT 2.0. As a temporary fix until you can get this SLS installed, slow your computer down during booting (many machines have a Turbo switch which can be turned off).
