I found an analog of the chip ds1488 and I ve sat it. I tried to connect to ARC by console port. On power on record "BOOT PROM Version 1.16 (Built on June 9th, 1998 at 12:24:24)" was appeared rapidly. Record "Loading kernel ... Ok" was appearead very slowly char by char in about 10 minutes. All that time Rn/Fl Led was flashing red. But after loading kernel system was loaded as usual fast. All tests and initializations was ok. Rn/Fl Led started green. Attempting auto-load from Flash was ok and then CLI started. I configured ip by quicksetup and connected by HARM through LAN. ARC looks good and configurable. But TCM cant resolve ARC?!?! And I cant ping NMC through ARCs Lan port. 10x in advance, Murad
