Hi!
I just installed Freedos 1.3 via USB. It works OK, but will not load the UDVD2 driver (it gets a #255 error). Will UIDE work instead? Or is the problem a bad HDD sector?
The problem probably is not a bad sector in your harddisk. If you want to access a CD/DVD after booting from that same boot CD/DVD, then you could also use the ELTORITO driver. For most other cases, you can use drivers like UDVD2. It might also make a difference whether you boot from USB or from harddisk (or SSD) as well. UIDE is newer than UDVD2. The newest versions of the drivers available with source are probably here: http://mercurycoding.com/downloads.html http://mercurycoding.com/downloads/DOS/drivers/2021-10-30/2021-10-30.zip This contains a 2015 rdisk (with rdiskon) and UDVD2, 2020 UIDE and xmgr (himem alternative), 2021 UHDD and a 2022 readme text file. UIDE supports both optical and non-optical drives as well as a cache. UHDD only does non-optical disks. UHDD contains a cache, too. UDVD2 only supports optical drives. UDVD2 can share the cache of UHDD if you load UDVD2 after UHDD. Note the readme regarding which drivers are best in which situation. Also note that depending on where you got that 255 error, it may mean XMS memory error! If that is what happened for you, then you may want to try different combinations of memory drivers such as JEMMEX, JEMM386, HIMEMX, XMGR etc. By default, your FreeDOS installation will already offer a few combinations in your boot menu. Try those :-) If your mainboard supports AHCI, it may belp to disable AHCI mode in your BIOS / CMOS settings. Alternatively, you can use AHCICD by the late R.

Japheth has created an unreal mode variant of it, too: https://github.com/Baron-von-Riedesel/AHCICDU You can also find updates for JEMM and HIMEMX on Japheth's GitHub "Baron von Riedesel", even his HIMEMSX to use more than 4 GB RAM :-) Regards, Eric _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
