Happily, I managed to get the card working.
The trick is, our test ring was faulty :-)
If you have the IBM Auto 16/4 ISA token ring adapter, with the
two lights on the pack, you must patch the driver.
In ibmtr.c, around line 280:
case TR_ISAPNP:
if (intr==0) irq=9;
if (intr==1) irq=3;
if (intr==2) irq=10;
if (intr==3) irq=11;
while(!(ti->mmio + ACA_OFFSET + ACA_RW + RRR_EVEN));
ti->sram=(unsigned char *)((unsigned long)(ti->mmio + ACA_OFFSET
Change the last line into:
ti->sram = NULL;
Then around line 390:
if (cardpresent==TR_ISA) { /* finish figuring the shared RAM
Change that to:
if (ti->sram == NULL) { /* finish...
This helped for us. Any specialists know why the assignment
of the shared RAM area fails?
