Insert the board into the bus master slot, and using the AutoSCSI utility:
If the boot disk is larger than 1 Gbyte, set the "Adapter BIOS Supports Space > 1 GB (DOS) only" option to Yes.
Put the adapter in ISA-compatible mode by setting the value for "Set Host Bus Adapter I/O Port Address as Default" to No.
Ensure the Advanced option "BIOS Support for > 2 Drives (DOS 5.0 or above)" is set to No.
Configure the IRQ and BIOS address values manually if your PCI motherboard is not fully PCI-specification compliant. If the system hangs while installing the Solaris software, do the following:
Check the IRQ jumpers on the motherboard, if any.
Run the CMOS utility to set the IRQ and BIOS addresses, if any.
Run the AutoSCSI utility.
All the settings should match each other. If you need to manually configure the BIOS address, you may have to check jumpers JP4 and JP5.
Insert the board into the bus master slot, and using the AutoSCSI utility:
If the boot disk is larger than 1 Gbyte, set the "Adapter BIOS Supports Space > 1 GB (DOS) only" option to Yes.
Choose the defaults, except set the 5.1 "BIOS Support for > 2 Drives (DOS 5.0 or above)" to No.
Follow these guidelines when adding a second Mylex PCI controller to a system.
The already installed PCI board must be the primary controller.
The primary controller must have an I/O address that precedes the secondary controller in "Supported Settings" (as listed from left to right). For example, the primary controller can use an I/O address of 0x234, as long as the secondary controller uses either 0x130 or 0x134. The I/O address of each board is determined by its slot. Try different slots until the first card works as the primary controller.
Disable the BIOS on the secondary controller.
Wide-mode PCI adapters will support targets greater than 7 if the proper entries are added to the system configuration files: /kernel/drv/sd.conf (for disk) and /kernel/drv/st.conf (for tape).
