Hp 21mx loader rom set

Thanks a lot. Anyone wants me to dump the DS/1000 rev 1826 ROMs or are these already available? What?s the CBL ROM? The one that?s on the cable interface card?

Does anyone know? Those are DS/1000 revision 1826. Page 3-130 of the HP "Communicator/1000 for Software Update 6.0" (5951-6201, December 1992) has a full list of the DS/1000 ROMs and revisions, as follows: 91740-80001/02/03/16 -- Rev. 1740 91740-80018/19/20/17 -- Rev. 1813 91740-80033/34/35/48 -- Rev. 1826 91740-80049/50/51/48 -- Rev. 1913 91740-80064/65/66/48 -- Rev. 2003 (bad ROMs; withdrawn) 91740-80067/68/69/48 -- Rev. 2003 (good ROMs) 91740-80070/71/72/48 -- Rev. 2540 (adds 7974 loader; no DS change) (The first three ROMs in each entry are the microcode ROMS; the fourth is the CBL ROM.) Pages 3-104 through 3-136 of that document give the firmware revisions of all of the HP products then in support. Anyhow, looking at the ROMs and dates, I suspect these are E/F microcode only and would not work on the 21MX. All of the above are E/F-Series only. -- Dave
