Figure F-l. Sample Configuration BQOPS.ASM Module

Each of the options in the sample configuration BQOPS.ASM module listed above is explained in the following paragraphs.

CPU

This option specifies the type of CPU used: 10 for iSBC 80/10

 

or 80/10A, 20 for iSBC 80/20 or 80/20-4, or 30 for iSBC

 

80/30. It is only referenced by the BQMEM.ASM module to

 

initiate interrupt polling for iSBC 80/10 based DFS systems

 

that are not boot loaded.

BOOTED

This option is used to allocate memory. It is 1 if the boot

 

loader is used, or 0 if a PROM-based BASIC-80 is generated.

TERMH

With this option, a 1 specifies the Full Terminal Handler, and

 

a 0 specifies the Mini Terminal Handler. The Mini Terminal

 

Handler requires less RAM and PROM space.

RATE

This option generates an RQRATE to specify a baud rate if

 

any non-zero value is given. For further information about

 

setting baud rates, refer to the RMX/SO User's Guide.

CONTR

This option specifies the type of disk controller used. 201

 

indicates an iSBC 201; 202 indicates an iSBC 202; 204 in-

 

dicates an iSBC 204; 206 indicates an iSBC 206.

DFS

This option specifies the number of DFS files you wish to

 

have open at the same time. Specifying 0 means that DFS is

 

not used.

UIO

This option enables your user-written I/O drivers if you

 

specify 1. See "Adding User-Written I/O Drivers" in this

 

Appendix for further details.

NFILES

This option specifies the combined number of DFS and user

 

files that may be open at once. The number must be greater

 

than or equal to the number specified in the DFS option.

HIRAM

This option specifies the highest RAM location available in

 

the hardware configuration.

BOTMEM

This option places boot loader RAM at the highest possible

 

location. This address should be 2BFH less than the address

 

given in HIRAM.
