[url]http://optimizr.dyndns.org/dos/index.html[/url] 23-Jan-22 /R deleted from XHDD/XDVD2/RDISK and added into XMGR. New /F switch added into XHDD/XDVD2/RDISK, to "free" reserved XMS when all drivers are loaded. These changes HOLD all reserved XMS memory, if other drivers (JEMM386 etc.) need their …

From my heart: Jack and I just want to make DOS better, no intentional personal attack on others, just plain problem want to solve. Many memory manager did have compatibility issue, especially HIMEMX and JEMMEX, both have quite serious problems. Quote an email from Jack (2019-04-9): JEMMEX was never …

1) Better use same capacitance "3300uF", 1500uF is too small. 2) Try other vendors (RS, Mouser, Digikey) for same capacitance 3) IMO, not the ESR value is important but not a critical part, since modern electrolytic ESR value not too bad 4) Temperature is a factor but it can be solve by improving …

I see many people complain XMGR did not compatible with games, XMGR really code from scratch and did not just like others, just modify HIMEM and done. XMGR remove many support for specific obsoleted 8086 BIOS support, so you can say it's not compatible with everything, however it's size is very …

Forward Jack's reply: I know what VOGONS is. I specifically put the /S2 2.5-MB cache in XHDD for their 4-MB 80386 users, and nobody had word 1 to say about it. Also, do note Johnson Lam's post on my behalf re: wny XHDD /B did not work for you, as you obviously did not "R.T.F.M"! I have never heard …

Depends on how to define "MAD", he's furious since nobody read the manual and claim his drivers (XHDD, XDVD2) not working. Please stand in his position and think if someone talk boldly about your program didn't work, just because he got the wrong way. And the drivers exist for many years with tons …

That's because /B is meant for use with UMBPCI. Good to know XDVD seems to be ok now, but try it with some disc based games. That's also where shsucdx seems to have issues. I'm Johnson Lam post the following for Jack R. Ellis, since he can't access the Vogons forum: I am the author of the XMGR/XHDD …

According to author Jack, XDMA (UDMA is more than 10 years ago) is not designed for any adapter card. "XHDD uses UltraDMA only on hard disks that identify themselves on the PCI bus as class 1 (storage), subclass 1 (IDE), that a a USB disk does not do, unless it were using some sort of USB-to-SATA or …

Done 😀

Hi, Try replace all the DOS driver with Jack R. Ellis driver, you may have surprise. 1) QCDROM.SYS was very old, seriously outdated, try XDVD2.SYS 2) XHDD.SYS replace SMARTDRV.SYS, it's faster! It had Read-Ahead, DMA/caching overlap, and other new updates. XHDD also offers caches down to 2.5-MB, for …

Please stop using UDMA.SYS, it's unstable and may ruin your data, I've another new post for the latest version XHDD.SYS, please check my post. http://optimizr.dyndns.org/dos/drivers.html

It seems that the latest UltraDMA driver or DOS did not made popular in the forum, as I host the driver for over 10 years, I'm quite surprise. The author Jack R. Ellis did notice some very outdated drivers talking around, the "UDMA 7.0" was seriously outdated and considered unstable. If you go to …
