Re: [Freedos-devel] FreeDOS package issues

Hi Jerome, 1) CPIDOS, this is basically just a package of codepage font files. Those files have been assembled in some fashion into the CPX files and distributed as such. However, there is no utility or information present in the package to create such CPX files. We should probably do

[Freedos-devel] UEFI, virtual BIOS and virtual hardware - was: Google Summer of Code?

2023-01-23 Thread E. Auer
Hi Bret, thanks for the great summary! For awhile, the UEFI manufacturers provided a CSM (Compatibility Support Module) as the "translation layer" so you didn't need a VM. But they've even stopped doing that nowadays. So, we'll either need to come up with a "generic CSM" that doesn't need a

Re: [Freedos-devel] Linking asm with C

2023-01-13 Thread E. Auer
hi! if you are using a protected mode model, it may be impossible to call int 10 directly and you may have to use dpmi for that. all compilers for DOS offer ways to call BIOS and other interrupts directly from C, which is a lot more foolproof than using ASM here. the next problem is whether

Hi Jerome, Here is the NEW general logic used by the installer in NORMAL mode. if the MBR for the target hard disk DOES NOT CONTAIN any boot code in the MBR, then ASSUME YES and overwrite it. if the MBR for the target hard disk has ANY KIND of boot code in the MBR, then PROMPT

[Freedos-devel] FreeDOS kernel DMA boundary handling versus I/O speed configurability request

2021-10-25 Thread E. Auer
Hi Jeremy, a last minute request for the new kernel release: In context of the patch for significant I/O speed improvements by only splitting transfers around DMA boundaries for drives where that actually is needed, based on the int 13.48 flags, please add a config sys option to override the

Re: [Freedos-devel] FreeDOS 1.3-RC5

Hi! Do we wait for a new KERNEL and FREECOM release? Jeremy was almost ready with those quite a while ago, It would be nice if RC5 had those. But, I don’t know how far off those are. Very nearby, I would say. If we don’t include updates for those in RC5, I don’t feel it would be wise

Hi Rugxulo, thanks, noticed kernel 2040 is listed on Ibiblio now as well. http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/dos/kernel/2040/ would you be able and willing to copy the kernel's changelog as it's in CVS/SVN right now, to above directory? DOS386 and/or Christian

Hi, Here it is (w/ srcs and one-byte diff): https://sites.google.com/site/rugxulo/XFDISK.ZIP?attredirects=0d=1 Nice size for a patch ;-) As for UPX terms, I could try LZMA and Ultra Brute settings indeed, but wonder what effect (decompression possible at all? loading times? memory

Hi! There was a question about the which of the algorithms (LZMA, NRV, UCL) is safe for GPL software. A quick review of the UPX web site did not give me a clear answer on which one was used when I specified -9 --8086 for options. Does anybody know off the top of their heads? I
