Abstract: ADAPTEC AHA-2940U2W WIDE ULTRA2 SCSI ADAPTER: NO DRIVER
TEXT:
No driver for Adaptec AHA-2940U2W Wide ULTRA2 SCSI Adapter.
SYMPTOMS:
ServerGuide 4.1 currently does not provide a driver for 'Adaptec AHA-2940U2W Wide ULTRA2 SCSI Adapter' resulting in Windows NT 4.0, Novell NetWare 4.11, SCO OpenServer 5.X and UnixWare 7.X cannot install to drives attached to this adapter.
PROBLEM ISOLATION AIDS:
- You can only use the Software Guide (Customized Installation with Set-up diskettes) method.
- SG will ask you to insert the NT CD.
- NT Set-up will show you a screen with two options while detecting the system devices, choose the following:
To specify additional SCSI adapters, CD-ROM drives, or special disk controllers for use with Windows NT, including those for which you have a device support disk from a mass storage device manufacturer, press S.
- Then Set-up asked to insert the disk labeled 'Manufacturer supplied hardware support disk' into drive A:.
- Insert the diskette with the drivers for NT.
- After that, the installation continued as usual and worked without problems.
- Novell NetWare 4.11
- SG won't list in the supported Adapters screen the Adaptec W2 PCI SCSI adapter, but if you continue will copy the rest of the new drivers required for your system, and then will prompt you to insert your Novell CD.
- Begin with the installation following the Novell set-up program prompts.
- When a screen appears that asks you to select a disk driver, press Insert.
- Insert the Adaptec 7800 Family Manager Set diskette for NetWare into your disk drive.
- Press F3 and specify the path to the aic78u2.ham driver for NetWare.
- Select AIC78U2.HAM and press Enter.
- Press Alt-ESC. From the console prompt type the following:
'load a:netwareiac78u2.ham'
- Press Enter.
- You may use Software Guide to install this card without requiring the new driver.
- SCO OpenServer 5.0.X.
- SG won't list in the supported Adapters screen the Adaptec W2 PCI SCSI adapter, but if you continue will provide you with the rest of new diskette drivers required for your system, then will prompt you to insert your SCO CD .
- An example of a valid boot string to use at the SCO boot prompt is:
restart link=blad325 Sdsk=blad(0,0,0) Srom=wd(0,0,0,0)
- After kernel loads but before it runs, 'link' prompts you to insert '7800 Family Manager' diskette.
Note: You will be notified that an existing aladinit driver already exists and asked which routine you wish to replace.
Choose routine 31 to replace and continue with the installation.
- SCO UnixWare 7.0.X
- Begin the installation.
- When a message appears asking if you want to install any HBA diskettes, insert the '7800 Family Manager' which contains the UnixWare Device Driver, then, select the INSTALL HBA DISKETTE.
- Continue with the installation.
