Is it possible to tack XTIDE onto the MB BIOS?
That would be very hard without source codes for the BIOS.
You can find C&T chipset drivers here. Maybe one of them can be used to enable shadow RAM. That way you wouldn't need to use emm386.
Is it possible to tack XTIDE onto the MB BIOS?
I'm not sure what caused this. I didn't have any problems with Master and Slave Drive combination but I did not try with only one drive. I tweaked the reset a bit more and tested on two different systems without problems. I hope it now works.
I have discovered that I can use a Sandisk CF/IDE converter with the Western Digital 9.06 overlay in place of less than 528MB hard drives.
I am also going to try the IDE to SATA converter adapters and a Western Digital 500GB SATA hard drive with the WD overlay to see if that will work as well.
Either of these will solve my problem w/o having to figure out why I have conflicts with the use of XTIDE and the machine's application software.
Thanks for the help.
I noticed my 486 DX2 66 box is taking longer to boot up
The BIOS on my site seems to be R476.
James, can you please send me a diff, or just all the source code with your modifications? Thanks...
1. What is XTIDE Universal BIOS version the James's BIOS is based on? What are the modifications? Is there a patch (or a modified source code) available?
archeocomp said:Hi all. I have just finished two XT-FDC boards. They work fine in my TurboXT taiwanese board with Super Turbo 2.5 Plasma's BIOS. I have a problem though. It might be XT-IDE BIOS related (I am using V2.0.0,Beta2)? Since I wanted three drives A: 1.44MB, B:1.2MB and ?: 360kB I attached the first two drives to primary connector and 360kB drive to secondary connector. Now when I configure Sergey's BIOS to use any two of the three drives it works fine. As soon as I configure third logical drive, the XT-IDE BIOS will not boot from IDE devices. It will write:
Booting C>>A
and the third FD (360kB) drive's LED gets on. My obvious question is, can I have three drives and still boot from what used to be C: drive before ?
It could be a bug in XT-IDE BIOS and it picks the third floppy drive (drive number 02h) instead of the hard drive (drive number 80h).
But I can not do this with XT-IDE BIOS 2.0.0B3.
It should read "Booting D>>D" since D is the first available letter for hard drive (I thought that is how DOS drive letters are assigned but you say third floppy drive is F?). BIOS always uses drive numbers so that does not explain other problems.Settings the number of drives to 3 makes it possibleto boot from C: It behaves like this: Booting D>>C
For some reason the drive numbers must point to wrong drive at some point. Did XTIDE Universal BIOS initialize before or after FD BIOS? You should try both ways. Another thing to try would be to build XTIDE Universal BIOS without serial floppy support (you can get the new build using the same link as before).I have three IDE partitions, one on a CF card and two on a IDE HDD. Only first two are recognized. More than that only the first C: partition has working filesystem. I can see directories on D: but not their contents. I believe this partition is treated like FAT12 ?? And the last problem is, my F:360kB is not recognized.
Sure, if nothing else helps.If you want I can send you one FDC card with Sergey's BIOS, so that you can set three FDDs in BIOS.
