41CL News
To fellow 41CL users ...
Just in case you have not noticed, Monte has released some days ago several CL ROM updates. This post will only cover the 41CL Update Functions, I will cover the other updates in another post later this week. 41CL Update Functions (Name: YUPS, Version: 4A, Released: 2018-12-28, YCRC: 0x5189B8F2) Warning: unless you manually download & activate the new update ROM (YUPS), this will only be available after you have completed your next update of your 41CL. The new YUPS ROM has a new tweak that speed up dramatically the outdated ROM scanning, were talking minutes instead of hours here. Monte has added a new flag called Enable Compare-only Mode that can be activated with the CPONLY instruction. (flag is reset at each power on) When the compare only mode is activated, the FLCHK?/FDBCHK? functions instead of calculating each ROM CRC, will compare the contents of the FLDB agains the content of the CFLDB to determine which pages are out-of-date. The result is simply amazing, V5 1024 ROMs scan time: 01m 16s with CPONLY set and 02h 51m 18s with CPONLY cleared. I have successfully updated my six 41CL without any issues. (1x V2, 1x V3, 2x V4 & 2x V5) Here is the most simple use case: Code: UPDATE 3B UPDATE 4A description For the most courageous manually loading the new UPDAT-4A.ROM image Code: steps description Code: "80F000-0FFF" UPDAT-4A.ROM will be loaded into RAM physical address 80F Many thanks goes to Monte Dalrymple for having added, in a transparent way, this new optimization into the 41CL Update ROM. Other thanks goes to Robert Prosperi for having beta tested the ROM. Have fun! Sylvain |
