Re: Boot from SRAM?
However, if I then connect my parallel port floppy drive to lpt1 and put in a DOS 5 disk, then sys a: the DOS 5 system files into a: and reboot, the card is not recognized as a boot disk. this may be caused by the fact that you need to start DOS 5 to run its sys.exe utility (doesn't it complain?). and you won't be able to start DOS 5 if you haven't got a SRAM card with DOS 5 on it. If this is the problem, I see no easy way out of this loop. First posting, so appologies if I've got the wrong end of the stick. Personally I would use the full form of the sys command and specify its path: Drive:\dos\sys Drive containing Dos 5 system files Drive you want to make bootable (Check the man^H^H^Hhelp page on that) You may have some success with attrib, del and copy on io.sys, msdos.sys and command.com, to swap Dos 3.3 files for Dos 5 files, but that's a pain.

I'll go look for it on the Elks site. yes, there should be a Readme in the images.zip file. if it isn't already there, it is surely at http://www.elks.ecs.soton.ac.uk/doc/ I can boot into DOS off the SRAM card. I just format the drive from DOS 3.3, sys a: the system files into it, and boot. aha. If you can do that, the rawrite.exe utility might too be able to do its work. you will find everything about it in the readme mentioned above.

Does anyone have an idea of whether it would be possible, and if so how I would go about it, to boot from an SRAM card? I have an old Sharp PC-3100 palmtop running DOS 3. in ROM that I'd like to try to use with Linux 8086. The PC can supposedly boot off an SRAM card. Failing that, what about booting off DOS 3.3 and then using loadlin to boot Linux? I guess I still need to be able to format the SRAM card, or a 10 MB flash RAM card I have, with the ext2 filesystem. I also have a floppy drive, but it is connected via the parallel port and uses a DOS driver to be seen. I am currently working with SRAM cards with a poqet PC machine from Fujitsu which Phil Kos sent me. I have so far managed to get Win95 to read these cards, but there does not appear to be Linux support for them. I should be able to write ELKS drivers for them without too much difficulty. I will let you know if I make any progress. Al
