The Wallstreet boots normally thenceforth.
please note that this is only necessary and only possible with a *new* WS Bluechip CPU. An already flashed one will only work with the same base model (WS or WS II (also named PDQ)) as it was flashed for. This was discussed recently in the threads "Re: Wallstreet processor mitch-match" and "Re: Wallstreet screen question". There was some disagreement on which ROM was available in the early and later 233's but my thoughts were: >>I have attempted to install a wallstreet II logic board and bottom. This was >>a no go.

So I think early 233's (L2 cacheless >with 66Mhz board I think and Rage II+ ), 250s and 292s (83 Mhz boards >with Rage II+) are interchangeable, as is later 233s (with L2 cache and >new 66Mhz boards I think and Rage LT Pro), 266s and 300s (I think same >66Mhz boards with Rage LT Pro). >Though as I haven't tested L2 cacheless 233s with a bluechip flashed for, >say, a 266, I'm not 100% sure, but this should be the case if the >determining factor is the ROM as Powerlogix have hinted to me. -- G-Books is sponsored by <http://lowendmac.com/> and...
