The following troubleshooting notes apply to all MBA environments.
Compatibility Problems with Option ROMs
for Hard Disk or SCSI Controllers
If your PC's BIOS is not BBS-compatible, then compatibility problems may arise
when using MBA in PCs that contain certain types of hard disk controller or SCSI
controllers, specifically those that have BIOS option ROMs on board.
MBA uses the same method as the hard disk or SCSI controller to control the PC's
boot process. The device that initiates this method last controls the boot process
for the PC and the other device is not usable. This is not a problem for PCs with a
BBS-compatible BIOS. Selecting Interrupt 19 or Interrupt 18 boot control may
solve these problems. Refer to
Table 5: Startup Options
for more information.
MBA Not Executing
Your MBA may not seem to be executing at all. If you do not see general MBA
messages displayed on the screen such as “Managed PC Boot Agent (MBA)”, the
MBA version number, and the 3Com copyright statement, it may be because your
PC has a BBS-compliant BIOS and the MBA is not positioned properly in the boot
order. Refer to “
Setting the Boot Order on PC's with BBS BIOS
” for an explanation
of how to do this. You may also have the Base Code disabled. See "
Table 5:
Startup Options
.”
