I have not posted on this forum in almost 5 months due to the rather VICIOUS attacks on me by Bret Johnson, Ralf Quint, and Tom Ehlert re: diskette detection in the UIDE drivers.
However, this post has now become necessary. Shown below is an E-Mail which I received early this morning, from Christian Pfaller of Germany (forwarded by Johnson Lam). Pfaller's problem is most likely a direct result of the logic I added with the 29-May-2012 UIDE, which tests for up to four diskettes using BIOS calls, instead of testing for only 2 via directly checking the BIOS diskette-flags byte. That change was made by me "under duress", i.e. by the above damn FleaDOS "pundits" INSISTING I obey the Ralf Brown lists and issue the BIOS calls, so damn "VirtualBox" could be run without its OWN diskette-detection problems getting CORRECTED!! Pfaller indicates the last UIDE version which worked with his LS120 drives was 20-May-2012, the version BEFORE I put in the diskette BIOS calls. I shall immediately PUT BACK the diskette test logic from the 20-May-2012 UIDE into the current UHDD/UIDE drivers. After appropriate checking by me, Johnson, and Christian Pfaller, I shall release an updated set of drivers on Johnson's website. Eric, if your "VBOXFIX" program is still available, you might want to re-issue it, with its specific logic to test the bits in the BIOS diskette flag byte for the presence of diskettes, when "VirtualBox" is used. I intend to use that byte again, and NOT use BIOS calls to check for diskettes! You may also want to INSIST that the "VirtualBox" emulator fools FIX their diskette-detection logic to post the BIOS diskette-flags byte properly, which would have AVOIDED all of this mess! Now, I will again "unsubscribe" from FD-User. And I hope NO ONE expects me to listen to any of its "pundits" ever again!! Jack R. Ellis ========================================================================= -------- Original Message -------- Subject: Problem with the UIDE Cache and "LS120" Diskette Drives. Date: Thu, 11 Oct 2012 20:03:58 +0000 From: MR-LEGO <mr-lego...@web.de> To: Jack R. Ellis [forwarded from johnsonlam...@gmail.com] Dear Mr Ellis. Thank you for your great drivers. They work very fine. But I have a problem with the UIDE cache in conjunction with an "LS120" Diskette Drive. I found the problem by checking three LS120 diskettes on last Friday. Yesterday and today I made some several tests with it. I use the latest version [2012-08-04] of UIDE. For example I load UIDE with the parameter "/S25" (with 25MB-cache). If I check now a LS120 diskette with DOSFSCHK, it told me that the first and the second FAT are not be the same. Now I load UIDE with the parameter "/B" (basic, without cache). Then I check the LS120 diskette with DOSFSCHK, no errors were found. If I make a 1:1 image of a LS120 diskette and UIDE-cache is loaded, the content of the image isn't the same as the diskette. Now I make a 1:1 image of a LS120 diskette without the UIDE-cache, the content of the image is the same as the diskette. This problem only appears with the "LS120" Diskette Drive. I tested UIDE under FreeDOS and MS-DOS and the result is the same. I tested it on another computer with another "LS120" Diskette Drive, too. The oldest version of UIDE [2012-05-20] I tested doesn't have this problem. Many thanks for your help.
