Tandy mode: Allow vertical total and display end to set all 8 bits, which is apparently needed for "Math Rabbit". It is unclear at this time if Tandy hardware really does take all 8 bits or is limited to the low 7 bits like MDA/CGA/PCjr/Hercules

INT 10h: The char height, video CTL, and video switch fields of the BIOS data area did not appear until EGA/VGA BIOSes came along. These fields are zero on MDA, CGA, Hercules, PCjr, and Tandy. Furthermore, Mindscape "Road Runner" requires the video CTL field to be zero in order to detect Tandy when machine=tandy.

PCjr: If memsize is 128KB or less, subtract 16KB from total memory at BIOS level, omit reserved graphics memory MCB block at the DOS level. Otherwise, report total memory and insert reserved MCB block as if PCjr with a sidecar that adds memory, which is also DOSBox SVN default and its only behavior

PCjr: Remove minimum 256KB check, allow setting as low as 64KB, although the DOS kernel still requires 128KB minimum. Fix DOS kernel not to create MCB block past video RAM at top of 128KB if memsize is 128KB. This change makes it possible to run Mickeys Space Adventure in PCjr mode if you set memsize=0 and memsizekb=128. Note the game will corrupt itself if memsize=144 to memsize=256 and will not display anything if memsize=640 which is equivalent to DOSBox SVN PCjr emulation

Tandy mode: Instead of fixing the 128KB region at 8000:0000, select the 128KB region according to the amount of conventional memory. Remove 384KB minimum E_Exit check, allow down to 64KB but warn if below 256KB.

After a discussion with others on the Vogons forums, it seems both Tandy and PCjr report memory size as real memory size minus 16KB, and it stays that way even if you later use the 32KB 16-color modes. Hope your program can keep the MCBs and important stuff out of the way!

Fix for Win 3.x corrupt Group files in FAT image files #2381
...
This is a fix for #2381 .
Month ago joncampbell fixed a FAT image problem: scandisk detected file length errors in some created files.
But this fix creates a problem with corrupted GRP files in windows 3.1x installations (see #1758 ).
With this new patch both problems are gone: no file size and no group file problems anymore.
The creation and extension of windows 3.1x group files is weird:
It's done with multiple position and write commands, some of them are writings of 1 or zero bytes at all.
