Here are my notes related to Tandy published roms and cold restarts. Aug. 5, 2009: * for Multiplan and IntSol, a patch was applied to replace "AB" with 00 00 hex at offset 0040, to avoid cold restarts when OS detects rom removal. * I think they are officially working fine.
So, what I did, is I modified the roms so that they would stop cold restarting. This was a "feature" of M100 power-on, was detection of inserted option roms and detection of removal. The roms are located here: https://bitchin100.com/wiki/images/2/2f/M100_OPTION_ROMSv2.zip On Thu, Feb 9, 2023 at 2:17 PM Comcast <[email protected]> wrote: > All, found this buried deep in an article on M100 ROM sockets > > Interesting observation about a potential difference with the Multiplan > ROM? > > Mike > > Sent from my iPhone > > Begin forwarded message: > > *From:* Michael Malecha <[email protected]> > *Date:* February 9, 2023 at 1:10:34 PM CST > *To:* Comcast <[email protected]> > *Subject:* *text* > > > > In the Model 100, pin 23 is labelled as a 2nd /CS (aka /CE), but is > connected to the ALE bus signal. > To be clear, I don't mean CS2, I mean a 2nd active-low /CS1.
