I've got that "Rescue" CD working (98se-OS-running-on-a-cd thingy), so anytime I totally lose all windows on HD, I can just pop in cd, win98se boots up AND RUNS COMPLETELY from the cd (and in RAM, of course), not using any HD space, and I instantly have win32 environment to use 7-zip to restore a backup to HD...
-works pretty good, tho VERY SLOOOOOW..... thinking about trying some tweaking, like loading most of it into RAM first, running the OS mostly from RAM instead of entirely from CD... -again, motivation issue...
-so, no REAL need for real-mode stuff, always have that OS-CD available... tho it takes FOREVER and a half to boot, so real-mode tools are preferable...
(oh yeah, I also keep an ancient 1gb HD with emergency safe win98se OS on it; more than once I've plugged that in, here and at friends' houses, actually quicker hooking that up as boot-drive than waiting for dam OS-CD to boot!
R u loading SMARTDRV from config.sys or autoexec.bat on that 98SE boot CD?
Because that CD [besides spinning way slower than a HD] loads probably only a minimal Windows GUI, and in that case probably doesn't have 32-bit disk/file cache enabled, so it runs in slower "MS-DOS compatibility mode". The only fix for that is smartdrv.
Example [for single HD/partition = C]:
- autoexec [no need to load it with LH, cuz smartdrv loads itself in UMA if it detects an UMA manager already resident in memory]:
SMARTDRV 12288 C+ /N /Q
-config:
INSTALLHIGH=SMARTDRV.EXE 12288 C+ /N /Q
This gives Windows 12 MB of disk cache, but works only in "MS-DOS compatibilty mode".
FYI: to load smartdrv "high" in config.sys [a.k.a. in the Upper Memory Area (UMA)], u need an UMA manager like UMBPCI, QEMM386, RM386, 386MAX or MS EMM386.EXE in config.sys.
UMBPCI [the best + it's free] requires compatible mobo chipset to work properly:

You can find more details on how to do this [and more DOS tweaks to maximize performance] in MEMORY.TXT, part of W95-11D.EXE [1.15 MB]:

Have fun.
