/**************************************************************************/
/* OS/A 1.4.0 */
/* */
/* The following kernel options are available: */
/* General options: */
/* ROM without ROM, all options are set in this file */
/* CMOSCPU for (Rockwell) CMOS CPU */
/* NMIDEV allows handling of NMIs in devices - without MMU only */
/* NMIRESET calls RESET when an NMI is received */
/* STACKCOPY without MMU, split stack in 2 pieces only and save */
/* task stack each time the context is switched */
/* Gives larger stack space per process and more */
/* processes but is slower */
/* */
/* Memory options: */
/* RAMSIZE Size of the RAM */
/* MIN_MEM minimum needed size of RAM to start */
/* ROMTEST if ROMTEST is defined, the MMU is not loaded, the RAM */
/* is not tested, and RAMSIZE is assumed to be the real */
/* RAM size. The memory blocks in MMU registers $8-$f */
/* are secured with GETBLK */
/* RAMTEST if set, the RAM from address 2 up is being tested up */
/* to RAMSIZE. If not set, RAMSIZE is assumed to be the */
/* real RAM size. */
/* If set, then BATMEM, MEMINIVAL, and NOMIRRORMEM can */
/* be used */
/* BATMEM during memory test the main memory is not cleared, */
/* the value is kept intact (for battery buffered RAM) */
/* NOMIRRORMEM can be set if definitely _no_ mirrored memory is */
/* there. Should definitely be set when a 32k RAM socket */
/* can be fed with an 8 kByte RAM. */
/* MEMINIVAL value to fill RAM with after RAM test (0 if not set) */
/* */
/* Architecture options: */
/* NOMMU computer without MMU */
/* NOSYSPORT computer without SYSPORT ($efe0) */
/* */
/* Architecture defines - these are defined in arch/x/devices/kinit.a65: */
/* LEDPORT Address of the port where an LED can be switched on */
/* LED_LED The bit of the LED in the LEDPORT. 0 means on, */
/* != 0 means off */
/* can be set to SYSPORT, SYS_LED for example */
/* H_ERROR If LEDPORT is not defined, then H_ERROR must be */
/* defined as routine to signal hardware errors */
/* INITIMER Routine to init kernel timer, i.e. the preemption */
/* timer */
/* CLRTIMER clear the irq line from the kernel timer signal */
/* */
