Re: [Freedos-user] FreeDOS is slow in Raspberry 4

Something to note in the original bug report is that CFLAGS chosen are not optimal for performance (`make 'CFLAGS=-Wall -g -O2 -w'`). Specifically, the `-g` and `-O2` flags should probably be changed. `-g` [0] adds debugging info which will make the QEMU binary larger, and produce code & data to

Hi: PROVOX loads fine, but it sends only "synth clear" (0x05) reset messages over COM1, for example when I press slash + L. It never sends me anything to actually read aloud. Did it talk to you? What key presses have you performed? I just booted into FreeDOS and it worked ok.  Pressing /l told me I

[Freedos-user] Why I chose ASAP in my custom distro build

Hi: Here's why I chose to include ASAP in my custom distro. It is true that the licensing model for Provox is probably the most compatible, as far as the distribution of packages with FreeDOS is concerned. Unfortunately, Provox's manual is sparse, to say the least. It's got the bare minimum, and, i

Re: [Freedos-user] Introducing myself, and inquiring about using FreeD OS as a blind user

Hi:  Now, going back to FreeDOS: the only improvement I can think of is to include some sort of screen reader into the distribution. That is why I was interested in the PROVOX option, since PROVOX appears to have a license perfectly compatible with FreeDOS. Sadly, I was unable to make it output any

FreeDOS is very, very slow on QEMU running in a Raspberry 4. It's drawing the screen line by line when I do a DIR on C:\, with only 7 directories and files in it. It's worse in full screen. For those of you that run FreeDOS on a Raspberry, can you offer a tip to make it go faster? Here is s

I'd also like to add that when I speak of a battle, I am in no way referring to a battle against anyone here, or any FreeDOS developer. The rather military term was strictly in reference to the effort of overcoming or circumventing technical limitations. Best, Felix Am Mi., 18. März 2020 um 10:22
